Seven priorities for near-term action were identified: • Developing an overarching national strategy to guide federal climate change adaptation programs. • Improving coordination of federal plans and programs. • Creating a federal climate information portal. • Creating a clearinghouse of best practices and toolkits for adaptation. • Including support for assessment in USGCRP agency budgets. • Increasing funding for research on vulnerability and impacts, including economic analyses, and pilot projects that join local, state, and regional governments and academic institutions to develop and test adaptation measures and tools. • Initiating a regional series of ongoing climate adaptation forums. 11 NASA Earth Observing Satellite Fleet - 2012 6 GCOM-W just joined A-train this summer; CloudSat returned to A—train this spring after having left during anomaly recovery NASA Satellite Fleet in Motion 14 7 Access to Remote and Hostile Areas The Lydonia 15 Major Sources That Are Virtually Unstudied in Southeast Asia (courtesy Bob Yokelson) Brick Kilns Trash Burning Crop Residue Fires Cooking Fires 8 Sea Surface Temperature: MODIS 17 Terra/MODIS, May 2001 Blended MODIS and QuikSCAT melt maps of the Greenland Ice Sheet Dorothy K. Hall* and Son V. Nghiem** *GSFC / Code 614.1, **JPL / Cal. Tech. Summary: We blended three daily products: MODIS albedo, MODIS land-surface temperature (LST) and QuikSCAT (QS) melt to quantify surface melt on the Greenland Ice Sheet. The products provide remarkably consistent results showing the locations of boundaries between surface melt and frozen conditions. The QS is more sensitive to melt than is the MODIS LST, with the QS detecting ~11% greater extent of melt, largely due to the capability of the QS to detect melt in snow near the surface as well as surface wetness. 2007 Melt Scientific significance: Before this work, it was not Season known which of the “boundaries” observed on the surface of the Greenland Ice Sheet were physically meaningful melt-zone boundaries, or artifacts of remote sensing. More precise measurement of melt progression and extent of melt enables improved quantification of meltwater runoff, and thus sea-level (A) Minimum albedo from MOD10A1 with the limit of rise when studied over a long time period. melt from QS included.

  • Correlation of the SAGE III on ISS Thermal Models in Thermal Desktop
    47th International Conference on Environmental Systems ICES-2017-171 16-20 July 2017, Charleston, South Carolina Correlation of the SAGE III on ISS Thermal Models in Thermal Desktop Ruth M. Amundsen1, Warren T. Davis2, and Kaitlin A. K. Liles3 NASA Langley Research Center, Hampton, VA, 23681 and Shawn C. McLeod4 Analytical Mechanics Associates, Inc., Hampton, VA, 23666 The Stratospheric Aerosol and Gas Experiment III (SAGE III) instrument is the fifth in a series of instruments developed for monitoring aerosols and gaseous constituents in the stratosphere and troposphere. SAGE III was launched on February 19, 2017 and mounted to the International Space Station (ISS) to begin its three-year mission. A detailed thermal model of the SAGE III payload, which consists of multiple subsystems, has been developed in Thermal Desktop (TD). Correlation of the thermal model is important since the payload will be expected to survive a three-year mission on ISS under varying thermal environments. Three major thermal vacuum (TVAC) tests were completed during the development of the SAGE III Instrument Payload (IP); two subsystem-level tests and a payload-level test. Additionally, a characterization TVAC test was performed in order to verify performance of a system of heater plates that was designed to allow the IP to achieve the required temperatures during payload-level testing; model correlation was performed for this test configuration as well as those including the SAGE III flight hardware. This document presents the methods that were used to correlate the SAGE III models to TVAC at the subsystem and IP level, including the approach for modeling the parts of the payload in the thermal chamber, generating pre-test predictions, and making adjustments to the model to align predictions with temperatures observed during testing.

  • SAGE III on ISS SPIE 2014 Paper FINAL
    The Stratospheric Aerosol and Gas Experiment (SAGE III) on the International Space Station (ISS) Mission Michael Cisewskia, Joseph Zawodnya, Joseph Gasbarrea, Richard Eckmanb, Nandkishore Topiwalab, Otilia Rodriguez-Alvarezc, Dianne Cheeka, Steve Halla a NASA Langley Research Center, 11 Langley Blvd, Hampton, VA, USA 23681 b NASA Headquarters, 300 E Street Southwest, Washington, DC 20546 c NASA Goddard Space Flight Center, 8800 Greenbelt Rd, Greenbelt, MD 20771 ABSTRACT The Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III/ISS) mission will provide the science community with high-vertical resolution and nearly global observations of ozone, aerosols, water vapor, nitrogen dioxide, and other trace gas species in the stratosphere and upper-troposphere. SAGE III/ISS measurements will extend the long-term Stratospheric Aerosol Measurement (SAM) and SAGE data record begun in the 1970s. The multi-decadal SAGE ozone and aerosol data sets have undergone intense scrutiny and are considered the international standard for accuracy and stability. SAGE data have been used to monitor the effectiveness of the Montreal Protocol. Key objectives of the mission are to assess the state of the recovery in the distribution of ozone, to re-establish the aerosol measurements needed by both climate and ozone models, and to gain further insight into key processes contributing to ozone and aerosol variability. The space station mid-inclination orbit allows for a large range in latitude sampling and nearly continuous communications with payloads. The SAGE III instrument is the fifth in a series of instruments developed for monitoring atmospheric constituents with high vertical resolution. The SAGE III instrument is a moderate resolution spectrometer covering wavelengths from 290 nm to 1550 nm.

In this study I seek to provide observations and understanding of sulphuric aerosols bound in the stratosphere from natural and possibly anthropogenic sources. Respectively draw attention to where the aerosols are located and why. The most intensive source of additional stratospheric aerosol loads stems from volcanic eruptions and in June 1991 Mt Pinatubo injected over 20 tonnes of SO2 into the troposphere and subsequently high up in the stratosphere.

This consultation event was co-ordinated by the Canadian Space Agency (CSA) in the context of the Government of Canada’s Innovation Agenda, and focussed on space exploration as an engine for innovation and a source for youth Science, Technology, Engineering and Mathematics (STEM) inspiration. This event highlighted science opportunities and advances in a number of technology fields such as optics, robotics, sensors and data, with potential for new application developments in various sectors including health. Workshop participants welcomed this event with much enthusiasm, as they recognised that a renewal of science priorities by the space exploration science community was well-timed to position Canada for future space exploration opportunities and to enable socio-economic growth. Sustaining Canadian Science Leadership and Excellence Canada has a legacy of excellence in space. For example, Canada’s normalised citation index for astronomy and astrophysics positions Canada as the leader in the Group of 7 (G7) in this field. As a result of strengths in many space sciences, Canada is often sought after for science and engineering contributions to international Space Exploration missions in space astronomy, planetary science and space health.
