Executive Summary
The Year Past The NSIDC DAAC sustained and expanded operational data processing from Earth Observing System (EOS) satellites in 2003. The EOS Core System (ECS) has kept up with the integrated data flows from TERRA, AQUA, and ICESat, and we are pleased with the ECS throughput and stability. Our data distribution has been slowly building. We are encouraged with science community interest in the MODIS snow and ice products and expect greater interest in the Advanced Microwave Scanning Radiometer- EOS (AMSR-E) data when these data are released to the science community. NSIDC kicked off the first significant reorganization since its inception in 1982. We hired a Deputy Director (Dr. Clark Judy) in mid-year 2003. We completed transition from the previous DAAC contract to a new five-year contract, extending operation of the NSIDC DAAC to April 2008.
The Year to Come The current Version 0 (V0) tape storage archive is nearing the end of its operational life. DAAC engineering staff will be conducting a trade study to determine the best migration path for NSIDC DAAC heritage data sets. At this point, two options are being considered; move all or a part of the data holdings into the ECS, or replace the V0 tape archive. It is possible to create a hybrid case where some data are migrated and a smaller replacement archive or more online disk space could be acquired. The DAAC continues to move data sets and services onto rotating disk. We intend to expand our current Redundant Array of Independent Disks (RAID) environment in the coming year. The schedule will be determined by funds and affordable RAID hardware. We expect user demand for EOS and V0 data to expand in the coming year. MODIS data products made steady gains in user popularity. AMSR-E products will come online in early 2004, and we assume they will be as popular as their Special Sensor Microwave/Imager (SSMI) predecessors. Geoscience Laser Altimeter System (GLAS) data are also expected to be more widely available. The NSIDC User Working Group strongly recommended that NSIDC host a workshop to review the passive microwave snow and sea ice products currently distributed. This workshop is tentatively planned for late January or early February 2004 in the Washington DC area. NSIDC DAAC scientists play a lead role in the development of a US National program for Climate in the Cryosphere (CliC), building on successful initiation of the World Climate Research Program (WCRP) CliC project. In January 2004, the US CliC planning meeting will be held in the Washington DC area. In addition to CliC, NSIDC scientists are involved in the planning for the International Polar Year (2007) and the next version of the Intergovernmental Panel on Climate Change (IPCC) Climate Assessment. On the organizational management front, one issue is on the FY04 horizon. Dr. Roger Barry, DAAC Scientist and NSIDC Director will take a one-semester sabbatical (January through July 2004).

1 Science Support Objectives
NSIDC at the University of Colorado at Boulder is the primary U.S. archive for snow and ice data. The co-located World Data Center (WDC) for Glaciology provides its principal international dimension. The NSIDC DAAC serves the polar oceans, ice, and snow research communities with data and data products generated from Earth observation satellites, as well as providing important in situ data sets. The NSIDC DAAC is an integral part of the multi-agency-funded efforts at NSIDC to provide snow and ice data management services. NSIDC DAAC processes, archives, and distributes sea-ice and snow-cover parameters from visible, infrared, and passive-microwave sensors, in particular from the Special Sensor Microwave/Imager (SSM/I), Moderate Resolution Imaging Spectroradiometer (MODIS), and Advanced Very High-Resolution Radiometer (AVHRR) sensors and related in situ data. From EOS Satellites, NSIDC DAAC archives and distributes data from the following sensors: Advanced Microwave Scanning Radiometer (AMSR), AMSR-E, and Geoscience Laser Altimeter System (GLAS).
1.1 Earth Observing System Data and Information System (EOSDIS) Mission Role Continental seasonal snow cover, sea ice, land ice, and frozen ground (collectively termed the cryosphere) are major components of the climate system and the global hydrologic cycle1. The cryosphere plays a major role in climate forcing and feedback, and responds sensitively to climate variability and change. There are many cryospheric indicators suitable for climate change detection and monitoring (as documented by the Global Terrestrial Observing System (GTOS) Terrestrial Observations Panel for Climate (TOPC) #32). Climate models require cryospheric data for model validation or sensitivity testing.
1.2 Objectives The primary goal of NSIDC DAAC is to serve communities identified by the Earth Science Enterprise Strategic Plan2, by providing easy and reliable access to EOS satellite data, ancillary in situ measurements, and any necessary baseline data, model results, and relevant algorithms relating to cryospheric and polar processes. These activities will evolve from the existing practices at the NSIDC DAAC to permit a smooth implementation of the EOSDIS Version 0 and transition to Version 2 of the ECS and beyond. Specific contractual science objectives are outlined in the NSIDC DAAC proposal dated June 23, 2003 (Sections 2.1 and 2.1, pp. 2-4), and are included by reference in the NSIDC DAAC contract signed September 31, 2003.

Section 1: Science Support Objectives 5
1.3 Guidance from the User Working Group The NSIDC DAAC receives regular guidance from the Polar DAAC User Working Group (PoDAG). The minutes of the almost-annual PoDAG meetings, along with their recommendations, are recorded on a web site located at http://nsidc.org/daac/. Guidance for fiscal year 2004/5 is as follows:
1.3.1 Action Items from PoDag 21 (October 2003) 1. User information/ metrics/accountability/FTP Produce user statistics of users and show them at the next PoDAG meeting. This should include File Transfer Protocol (FTP) transfers as well as other forms of data acquisitions by users of the DAAC. Publication/citations might be another way to show use of the data. The underlining concern is that the DAAC needs to be able to show its “worth to the community” and that this information can be used for future decisions. 2. Web site/gateway Re-evaluate the web site. The current site is not easy to navigate especially for more general users. It was thought that the data source could be more transparent to the user. Drop down menus (e.g. Talbots web site) could be used to make the site more snazzy. In addition, data novices should test any new development. Current/hot topics also need to be added so that individuals will want to visit the site regularly for information, not just to acquire data. 3. State of the Cryosphere Update it regularly - currently time series in the text end in 1999, although discussion is given about the ice conditions in 2002. Current events could also be given in this page. This page should be used as a one-stop location for information for the next IPCC report. The page also needs to be visually appealing/entertaining, with animations. 4. Become much more proactive in selling the Cryosphere and NSIDC role as the primary data center
The DAAC/NSIDC needs to be more aggressive in the following areas: a. Outreach to the general public, such as frequent media exposure, etc. b. Promoting upcoming missions, such as Aquarius, Hyrdo, National Polar- orbiting Operational Environmental Satellite System (NPOESS), etc. c. Promoting NSIDC data archiving and distribution skills 5. Passive microwave data sets Converge the plethora of overlapping data sets, especially dealing with sea ice. P.M. Abdalati proposed a workshop for this, with results to be reported to PoDAG.
Section 1: Science Support Objectives 6
6. Polar meteorological observations Interagency support for their assembly, quality control, and distribution. SEARCH Open Science Meeting: · NSIDC should participate in the Arctic Geographic Information System (GIS) session. · NSIDC should be promoting its polar data sets. · NSIDC should be promoting its data archiving and distribution skills.
7. Program in Arctic Regional Climate Assessment (PARCA) data sets: An assessment of the all the PARCA data sets needs to be complied. This assessment should include which data sets need to be migrated to NSIDC, with cost estimates.
1.4 Guidance from Program Scientist Dr. Waleed Abdalati is the current HQ Program Scientist. He will review the submitted copy of this Work Plan and provide comments and guidance directly to NSIDC and Earth Science Data and Information System (ESDIS). Should NSIDC revise this Work Plan in the course of FY04, his review comments will be added.

2.4.2 Milestone Summary In the FY03 Work Plan submitted in October 2002, NSIDC DAAC listed 164 milestones (see table 6.2). Of these, 128 were satisfactorily completed, 14 were not completed, 15 were delayed for mostly external reasons, and 7 were overcome by events and are no longer valid milestones. A more complete report will be forwarded by e-mail by the end of the first quarter of FY04.
2.4.3 DSE Final Report: MODIS Search and Order Project The MODIS search and order project proposed to develop a web-based search and order tool to search MODIS tiled data by tile ID instead of searching spatially. Since spatial searching was historically extremely slow we thought that search by tile ID would be faster. In the time between the submission of the proposal and the grant award (about 18 months) the performance of spatial search for tiled data improved dramatically, and the tile IDs are lumped in with all the other PSAs in the database so there is unnecessary overhead involved in tile ID searching. The end result is that search by tile ID is currently slower than spatial search. Searching for data by tile ID is, however, much more accurate. MODIS Search 'n' Order Web Interface (SNOWI) searches the NSIDC DAAC holdings for MODIS level 3 tiled data by date/time range, dataset ID, and tile range. Tiles covering the user’s area of interest can be selected using a java applet that enables drawing a bounding box on the appropriate grid, or by entering those values in text fields. MODIS SNOWI communicates with the ECS system via the V0 gateway for both search and order. MODIS SNOWI is now on NISDC's operational site at http://nsidc.org/data/modis_snowi/. The task details in the FY03 work plan stated that we would search by local granule ID, not tile ID. This proved to be impossible because the local granule ID contains the processing date/time. So there is no way to predict the local granule ID without running some sort of pre-search on a local database. It was also proposed that we would use an interactive orbit map to determine times for level2 data to translate into a local granule ID. Neglecting the local granule ID, we could still use that mechanism to change a spatial search into a temporal search - but it would require a huge amount of backend infrastructure that would need daily maintenance. So
Section 3: Fiscal Year 2003-2004 Plans 11
the development cost would be more than the original proposal for little benefit. We decided to implement the SNOWI approach instead. As of the end of FY03, the SNOWI interface is installed as an operational prototype. Users may now use it, but with the understanding that development will continue. As resources permit, we will improve performance and reliability.
Section 3: Fiscal Year 2003-2004 Plans 12
3 Fiscal Year 2004 - 2005 Plans
Section 3 describes our planned activities for FY04 and FY05 and the succeeding five fiscal years through FY09. The resources necessary to complete these projects are listed in Section 4. In this and subsequent sections narrative text is provided to explain the listed tasks and milestones. Milestones and proposed metrics may be found in tables located in Section 6. The NSIDC DAAC Contract Work Breakdown Structure (WBS) dictates the structural headings found in this section. NSIDC DAAC projects are managed in a complete, end- to-end fashion with all the components integrated. In addition to these data activities, the DAAC supports development, infrastructure, and management functions not specifically tied to a data set.
3.1 Science Operations The DAAC will continue to ingest, produce, archive, and distribute data and information related to the cryosphere. During the FY04-05 time period, the DAAC will maintain and operate both the non-ECS and the ECS data systems. Maintenance and operations activities required to support EOS and non-EOS missions is detailed in the following subsections. The data flows of EOS missions are depicted in the following flow chart.

3.1.2 AMSR-E Level 1A and derived science products are ingested and archived at the NSIDC DAAC. The DAAC acquires and archives the Level 0 data from EOS Data and Operations System (EDOS). Several of the AMSR-E products lie outside the cryospheric discipline. These products offer a special challenge to the science staff of the NSIDC DAAC. We have established linkages with the AMSR (non-cryosphere) science team for support of these products. The Mission Support of the AMSR products into the DAAC will involve the following activities: · Maintain active contact with AMSR Science Team and Science Investigator-Led Processing System (SIPS) · Develop contacts with non-cryosphere members of the AMSR team and the scientific community so that the NSIDC DAAC user services staff can deal with the non-cryosphere data sets produced · Provide technical support as needed by U.S. AMSR Science Team and AMSR SIPS (e.g. metadata descriptor files) · Assist AMSR SIPS Team with writing, editing, and reviewing required documentation · Increase awareness of AMSR-E data products and potential research applications; foster cooperative research endeavors · Maintain Earth Science Data Types (ESDTs) · Ingest data - Ingest Level 0 data from EDOS - Ingest Level 1A data from National Space Development Agency (NASDA)/Jet Propulsion Lab (JPL) - Ingest Level 2 and Level 3 products from Marshall Space Flight Center (MSFC) SIPS · Continue science operations · Conduct operational non-science quality assurance of data and products · Release data to public
Section 3: Fiscal Year 2003-2004 Plans 16
3.1.3 AMSR on ADEOS II The Advanced Earth Observing Satellite (ADEOS)-II satellite has ceased to operate. Planned NSIDC activities to acquire and distribute AMSR data have been stopped.
3.1.4 ICESat NSIDC DAAC archives and distributes GLAS data in the EOS era. Tasks to be completed before receipt of GLAS data include developing the required metadata configuration files to define the corresponding GLAS ESDT, and to configure the ECS insertion process to obtain the data from EDOS and the ICESat SIPs. Scientific quality assurance of GLAS data products is the responsibility of the GLAS Instrument Team. Objectives · Finish documentation. DIFs are finished and under extensive review currently. The DIFs will all need to be edited again, since ESDT parameters may change. There are three guide documents: one for altimetric products, one for atmospheric products, and one for GLA16. We anticipate last-minute changes to the documentation after GLAS is on orbit, particularly changes to atmospheric products. Our tasks include: · Ensure that NSIDC is ready and able to ingest GLAS data · Increase awareness of GLAS data products and potential research applications · Review currently available data access tools and suggest modification and/or development of new or enhanced tools. · Maintain and update ESDTs · Conduct operations readiness tests - Test search and order and subscription capability - Test operational non-science quality assurance procedures · Conduct end-to-end tests · Ingest data and products · Conduct quality assurance of data and products · Release data to the public
3.1.5 MODIS - Terra The NSIDC DAAC archives MODIS Level 2 and 3 snow and sea ice products using the ECS configuration. Level 2 and Level 3 snow and sea ice products are acquired from the MODIS Adaptive Processing System (MODAPS) via the Product Delivery Record (PDR) server at the GSFC DAAC. All MODIS Level 2 and Level 3 snow and sea ice products are archived by the NSIDC DAAC. Additionally, the NISE product is ingested into ECS and made available for MODIS and Multiangle Imaging Spectroradiometer (MISR) Product Generation Executables (PGEs) via subscription service. ECS subsystems will provide search, order and distribution services for the user communities. Activities that relate to operating the ECS in support of the TERRA Mission are listed below. · Install, maintain and update ESDTs · Conduct operations readiness tests Section 3: Fiscal Year 2003-2004 Plans 17

3.1.7.4 Global Snow Water Equivalent Time Series and Climatology We plan to release a monthly time series and climatology product (Aug. 1987-present) in early FY04. Armstrong and Brodzik will be presenting their methods along with examples of the data set at AGU December 2002. This data set is being developed under a research grant with DAAC distribution support. Their work has resulted in a steadily improving series of snow water equivalent (SWE) algorithms for SSM/I. They started with a modification of the algorithm developed by Chang, et al. for SMMR4. This is the “NSIDC1” algorithm used in NISE. They then improved on this algorithm by incorporating precipitation filters from Grody and Basist at the National Oceanic and Atmospheric Administration (NOAA), a correction for low SWE in known forested areas developed by NASA's Chang, Foster, and Hall after the Boreal Ecosystem-Atmosphere Study (BOREAS) field campaign, and by merging with snow cover described in our Northern Hemisphere Snow Cover and Sea Ice Extent product to better capture early fall shallow snow cover. This resultant “NSIDC7” algorithm will be used for the final product. This product helps address several of the National Research Council’s (NRC) priority measurements and their recommendation on time series and data coherence. Surprisingly, global snow water equivalent was not identified as a data gap. · Release first version of the Global SWE product, January 2003 · Planning for distribution routine distribution of products
3.1.8 Visible Infrared
3.1.8.1 AVHRR NSIDC DAAC will continue archival and distribution of these products as they are generated. Work will continue on filling temporal gaps in the data set.

3.1.9.1 RAMP In collaboration with Ohio State University, the Alaska Synthetic Aperture Radar (SAR) Facility, JPL, and VEXCEL Corp., NSIDC DAAC has participated in a program to map Antarctica using data from the SAR on the Canadian Radarsat, launched in 1996. The mapping mission is now complete. NSIDC DAAC's main function is to provide access to high-quality Digital Elevation Map (DEM) products, and to provide long-term archival and assistance in the distribution of the high-level SAR-mosaic products. The Byrd Polar Research Center at Ohio State University, in Columbus, Ohio, is the leading organization for this project. This project has transitioned to science operations. Our current task is to continue contact with the ASF and Ohio State groups so that NSIDC products remain up to date. · Maintain RAMP web site · Maintain routine distribution of RAMP DEM and mosaics housed at NSIDC
Section 3: Fiscal Year 2003-2004 Plans 22
3.1.10 In Situ Data Sets In situ data sets continue to grow at a moderate pace. It is our expectation that validation and calibration data sets will be acquired in support of the EOS and other missions of the NASA Earth Science Enterprise (ESE). Additions and/or updates to the NSIDC DAAC in situ data sets are determined by joint agreement between DAAC Management, NSIDC oversight board(s) and the PoDAG. Tasks: · Ingest and document aerial photos of sea ice - these were used for validating passive microwave sea ice algorithms (complete by 10/04). · Assess status of DAAC affiliated in-situ data sets that currently are in lower priority status. Determine whether these data warrant improved documentation and access or conversely should be placed in an inactive archival status.
3.1.10.1 PARCA Data Sets The Program in Arctic Regional Climate Assessment (PARCA), funded jointly by NASA and NSF to measure surface parameters of the Greenland Ice Sheet, has generated moderate volumes of data from automated weather stations, surface transects, ice cores, etc. These data are currently housed with the principal investigators. We currently collect metadata and operate a web-based access page, but the investigators hold the actual data and deliver directly to users. We may have an expanded and more direct role in later years should the PARCA investigators relinquish their current archival and distribution responsibilities. Task: Contact current PARCA investigators to determine status of their holdings, and to determine whether or not they wish to have their data transitioned to the NSIDC DAAC or some other data center
3.1.11 Validation

3.1.11.2 AMSR-E Validation Data Coordination The NASA AMSR science team has requested the NSIDC DAAC to ingest, manage, and distribute data sets that were collected for or support the AMSR-E validation effort. The objective of this effort is to design, develop, and operate a portal to data and information collected during the NASA’s AMSR-E Validation Program. The proposed portal will be modeled after the Tropical Rainfall Measuring Mission (TRMM) Global Validation web site now operated at the NASA Goddard Space Flight Center. The AMSR-E validation portal will be designed to support information exchange between each of the campaign’s participants in the pre-campaign planning stage. During the field experiment stage, the portal will have the ability to accept both post-flight summary data sets and field reports. After the completion of a field campaign, the data system will archive the quality controlled, investigator-approved AMSR-E validation data sets and distribute them to AMSR-E research scientists, earth scientists, and the general public without restrictions. NSIDC DAAC also participated in the Cold Lands Processes field studies, winter 2001/02 and 2002/03. NSIDC provided data management services for the field data, initially with support from the CLP project, and subsequently with support from the AMSR Validation Coordination effort. The NSIDC DAAC currently provides the following services: · Provides web services and data archival infrastructure support · Provides access to each data set as specified in respective MOU (CLP access will be determined by CLP team) · Archives data delivered to NSIDC according to DAAC standards on a schedule laid out in each data transfer agreement · Ensures basic preservation, access, and documentation (spirit of DAAC standards) of data held elsewhere · Provides general information about the investigators and validation campaigns and their importance for past or ongoing experiments and prior to beginning of future experiment · Supports logistics and communication needs of the campaigns as specified in respective MOU

3.1.13 Special Science Projects
3.1.13.1 NPOESS/NPP Mission Data Related to Cryosphere The NPOESS and NPOESS Preparatory Project (NPP) Missions will produce data sets of interest to the NASA cryospheric community. At this time NSIDC does not have a clear understanding of how these data streams will reach our community. We intend to lobby for a role in snow and ice product generation, archival, and distribution with the NPOESS teams at Goddard and NOAA. We expect expanded activity in the coming two years. Our goals are to: · Determine which sensor systems have high relevancy to NASA-sponsored polar science programs · Assess data management resource demand on the NSIDC DAAC with the NPOESS/NPP program staff and present a project to PoDAG and ESDIS for funding · Evaluate NPOESS as the future alternative to MODIS snow and ice products, (and AVHRR products produced by NSIDC)
3.1.13.2 Global Land Ice Measurements from Space (GLIMS) GLIMS is a cooperative effort with regional partners who are specialists in the study of selected "glacierized" regions and individual glaciers. The partners will utilize data from ASTER and other instruments to routinely map glacier surface area, length, width, ablation area, and ice motion vectors. This will lead to a more comprehensive world
Section 3: Fiscal Year 2003-2004 Plans 26
glacier inventory. Currently only 44 percent of the approximately 160,000 glaciers are documented. ASTER will provide a global source of well-calibrated, high-resolution data for glaciological studies using visible, near infrared and thermal infrared data. NSIDC DAAC is assisting with the provision of glacier inventory data for validation and will archive the derived products. The actual images will be available as part of the ASTER holdings at the EDC DAAC. The initial developmental activity has ended, and will be augmented by the recently funded Research, Education, and Applications Solutions Network Cooperative Agreement Notice (ReaSON CAN) award to the GLIMS team. The NSIDC DAAC will provide basic computing infrastructure (data servers, limited data storage space, web services) to the GLIMS effort. The ReaSON CAN project will fund all development activities. The DAAC will retain the GLIMS data sets at the end of the ReaSON can period of performance, funds permitting.
NSIDC DAAC tasks are listed below. · Plan for transition of maintenance and operation of the GLIMS database to the DAAC · Investigate development of new GIS products
3.1.13.3 ReaSON CAN We are collaborating with several ReaSON CAN proposals. The DAAC’s role is to provide counsel on data management issues, and possibly with external funding, data archival. NSIDC is a participant in three successful ReaSON CAN projects. · GLIMS: The proposal will provide limited data management and archival resources for the derived products of this global glacier study. · Polar Scatterometry: NSIDC scientist Dr. J Stroeve is a co-investigator on this proposal to the University of Utah. NSIDC DAAC will receive scatterometry products developed under this proposal. Limited resources will be available to archive and distribute these products. · Snow Cover High Resolution Products: Dr. J Dozier expects to archive the derived snow cover products from this proposal. More importantly, NSIDC DAAC will participate in the development and experimentation of distributed data management via the Microsoft TerraServer technology partner.
3.1.13.4 International Linkages One of the important mechanisms that the NSIDC DAAC uses to collect information on data needs of the cryospheric community is to participate in national and international scientific committees. Current and planned activities are listed below. The CliC Task Group has developed a Science and Coordination Plan and a draft implementation plan and implementation strategy for the World Climate Research Program (WCRP) CliC project, 2000-2015. It addresses global and regional cryospheric studies to ensure accurate and appropriate treatment in climate models of cryospheric processes and the interactions of the cryosphere with atmosphere, oceans, and land surface. In 2003, the new CliC Science Steering Group will develop specific project proposals for implementation through national and international programs. The group will
Section 3: Fiscal Year 2003-2004 Plans 27
organize preparation of the global and regional cryospheric data sets necessary for forcing and validating climate models and for diagnostic studies of the cryosphere’s role in climate. U.S. contributions to CliC are under consideration both by agencies (NSF, NASA, NOAA) and by a new (January 2004) Scientific Coordination Committee for the US CliC and by the Climate Research Committee of the NRC. The DAAC Scientist (Roger Barry) is Co-Vice Chair of the new Science Steering Group for the CliC. The CliC project is part of an international effort jointly supported by the World Meteorological Organization (WMO), the International Council of Scientific Unions (ICSU), and the Intergovernmental Oceanographic Commission (IOC) of United Nations Educational, Scientific, and Cultural Organization (UNESCO) to further scientific understanding of the climate system. These international programs provide guidance to the NSIDC DAAC on data set priorities. Specific tasks are listed below. · Attend Science Steering Group of CLIC in St. Petersburg, Russia, Nov 2003 · Circulate plans for key data sets in support of CLIC to WCRP and science community · Define what data sets are needed to answer scientific questions or develop new areas of scientific research · Develop a U.S. National program for CliC – Attend inaugural meeting of a Scientific Coordination Committee for US CliC program (January 2004) · Identify U.S. researchers with data sets relevant to CliC research interests, and obtain researcher agreements to make their data available to CliC researchers. · Attend the first CliC Science Conference in early 2005 (to be held in China or Europe) WCRP is implementing the Global Climate Observing System (GCOS)/ Global Terrestrial Observing System (GTOS). As a member of the Terrestrial Observations Panel for Climate (TOPC) of GCOS/GTOS, DAAC scientists are playing an active role in defining cryospheric indices and contributing to the identification of initial observing networks for key cryospheric components5. Participation in an IPCC/GCOS meeting (August 2002) in Boulder addressed the Second Adequacy Report on Global Observational Networks being prepared for the Subsidiary Board for Science and Technology Assessment of the U.N. Framework Convention on Climate Conference of the Parties in 2003. A TOPC meeting will be held in December 2003, to review TOPC activities in light of the Conference of Parties and the adequacy report on observations. For terrestrial components these are: glaciers and ice caps, ice sheets, snow cover, freeze-up/break-up of lakes/rivers and frozen ground/permafrost. Global Terrestrial Networks (GTNs) for glaciers and permafrost are being implemented. The GTN for Glaciers plans to rely heavily on the proposed Global Land Ice Measurement from Space (GLIMS) project to establish a comprehensive world glacier inventory using Landsat-7 and ASTER data. The GTN for Permafrost, being operated through the International Permafrost Association, includes a network of measurements of maximum active layer thickness and ground temperature in boreholes in permafrost.

The DAAC Scientist is co-chair of the International Permafrost Association (IPA) Standing Committee on Data, Information, and Communication. The European Geophysical Society (EGS) has developed an active group on cryospheric research. There were numerous cryospheric sessions at the Joint EGS-AGU conference in 2003 and a similarly ambitious program is planned for April 2004. NSIDC scientists are participating in an effort by the International Commission on Snow and Ice (ICSI) to achieve association status for the cryospheric sciences within the International Union of Geophysics and Geodetics (IUGG). A report has been prepared and a submission was made to the IUGG Executive Committee at the Sapporo meeting. Further discussions are expected during 2004-7.
3.1.13.5 Canadian Climate and the Cryosphere (CRYSYS) Program CRYSYS originated as a peer-reviewed foreign Interdisciplinary Science Investigation as part of NASA EOS. It is a recent award winner in the NASA IDS competition. This contribution to EOS is hosted and funded by Canadian agencies and universities, with the lead being the Meteorological Service of Canada (MSC). MSC funds in-house cryospheric studies and provides funding support to University partners through competitive peer reviewed applications. The Canadian Space Agency (CSA) became a CRYSYS funding partner in FY00-01, which has allowed an increased emphasis on the application of satellite technology for monitoring the cryosphere. In particular, CSA support has been instrumental in establishing a GLIMS regional center for the Canadian Arctic Islands at the University of Alberta, and in providing Radar Satellite (Radarsat) data to the CRYSYS team for developing new monitoring techniques. CSA has also been a major funding partner in the development of the Canadian Cryosphere Information Network (CCIN) at the University of Waterloo. The CCIN is of specific importance to the NSIDC DAAC as it is proposed to link CCIN to the DAAC. This will enable the sharing of Canadian cryospheric and related datasets. We are investigating a partnership, which would permit DAAC EOS dataset distribution through the CCIN. In FY04-05 we expect continued collaboration with CRYSYS and specifically the CCIN. Current tasks: · Attend CRYSYS Team meetings (February 2004) · Develop collaborations where appropriate and funds permit
Section 3: Fiscal Year 2003-2004 Plans 29
3.1.14 Long-Term Archival The long-term archive (LTA) plan for NSIDC DAAC data sets is to transfer them to NOAA per the transition plan currently under development by the NASA-NOAA study team. NSIDC anticipates eventual transfer of responsibility for these data sets to NOAA. We assume that NOAA and NASA management will choose the archive in place as a near-term option. NSIDC’s “NOAA at NSIDC” program will be the transfer vehicle and no data will be transferred to the NOAA LTA in FY04/05. The NSIDC DAAC will therefore concentrate on short-term preservation of our NASA data, both EOS and non-EOS (heritage) data. We will also continue to participate in the LTA implementation effort and to support other life-cycle planning efforts as needed (e.g., SEEDS) NSIDC formed an internal Long-Term Archival team in FY02, with participation from each data center program under the broader NSDIC umbrella. This team is responsible for defining NSIDC-wide archive standards and policies, as well as for developing an NSIDC-wide Archive Management Plan. As one of the data centers under the NSIDC umbrella, DAAC personnel participate in these activities as members of this team. Activities for FY 04 include: 1. Track and, where possible, favorably influence NASA and NOAA archive management policies and plans in regards to current or potential NSIDC data holdings. a. Establish and maintain close ties with NOAA and NASA management b. Attend SEEDS workshops and meetings, as well as responding to SEEDS related requests in regards to data lifecycles c. Respond to changes in NOAA and NASA policies and direction as needed 2. Refine NSIDC-wide archive management policies and standards 3. Participate in the definition and development of NSIDC-wide dataset metadata repositories 4. Prepare and present a presentation at the fall AGU on Virtual Repositories 5. Prepare and present a tutorial on Long-Term Preservation in a Distributed Environment for the spring IEEE Mass Storage Conference Additionally NSIDC’s archive management services group is responsible for: 1. Developing and maintaining operational metadata about NSIDC’s DAAC data holdings 2. Investigating NSIDC’s DAAC data holdings with the intent of determining status, location, priority and stabilizing the media upon which it is stored 3. Establishing and maintaining off-site backups for critical NSIDC DAAC data holdings NSIDC’s Timberwolf archive, which contains most of the NSIDC DAAC heritage/Version 0 data sets, is nearly full and its technology is near end of life. In FY04 a trade study will be performed to determine the most cost effective approach for handling this archive, this includes options for migrating the data into the ECS system as well as other options. (See Systems Engineering.)
