The Contribution of Global Ocean Observation of Continuity of HY-2
CGMS-XXXVI-CNSA-WP-04 Prepared by CNSA Agenda Item: III/3&4 The contribution of global ocean observation of continuity of HY-2 satellite HY-2 satellite, an ocean dynamic environment observation satellite, mainly ` objective is monitoring and detecting the parameters of ocean dynamic environment. These parameters include sea surface wind fields, sea surface height, wave height, gravity field, ocean circulation and sea surface temperature etc. The contribution of global ocean observation of continuity of HY-2 satellite 1. Introduction HY-2 satellite scatterometer provides sea surface wind fields, which can offset the observation gap of the plan of global scatterometer. At the same time, HY-2 satellite altimeter provides sea surface height, significant wave height, sea surface wind speed and polar ice sheet elevation, which can offset the observation gap of the plan of global altimeter around 2012, and can offset the observation gap of JASON-1&2 at polar area. More details as follows. 2. Observation of sea surface wind fields The analysis accuracy of wind field for ocean-atmosphere can improve 10-20% by using the satellite scatterometer data, by which can improve greatly the quality of initial wind field of numerical atmospheric forecast model in coastal ocean. Satellite scatterometer data has play important role on study of large-scale ocean phenomenon, such as sea-air interactions, ocean circulation, EI Nino etc. The figure 1 shows that QuikSCAT scatterometer has operational application in 1999, but it has not the following plan. ERS-2 scatterometer mission has transferred to METOP ASCAT in 2006. GCOM-B1 will launch in 2008, one of its payloads is an ocean vector wind measurement (OVWM) instruments, and it also called AlphaScat. -

Statement by Lynn Cline, United States Representative on Agenda
Statement by Kevin Conole, United States Representative, on Agenda Item 7, “Matters Related to Remote Sensing of the Earth by Satellite, Including Applications for Developing Countries and Monitoring of the Earth’s Environment” -- February 12, 2020 Thank you, Madame Chair and distinguished delegates. The United States is committed to maintaining space as a stable and productive environment for the peaceful uses of all nations, including the uses of space-based observation and monitoring of the Earth’s environment. The U.S. civil space agencies partner to achieve this goal. NASA continues to operate numerous satellites focused on the science of Earth’s surface and interior, water and energy cycles, and climate. The National Oceanic and Atmospheric Administration (or NOAA) operates polar- orbiting, geostationary, and deep space terrestrial and space weather satellites. The U.S. Geological Survey (or USGS) operates the Landsat series of land-imaging satellites, extending the nearly forty-eight year global land record and serving a variety of public uses. This constellation of research and operational satellites provides the world with high-resolution, high-accuracy, and sustained Earth observation. Madame Chair, I will now briefly update the subcommittee on a few of our most recent accomplishments under this agenda item. After a very productive year of satellite launches in 2018, in 2019 NASA brought the following capabilities on- line for research and application users. The ECOsystem Spaceborne Thermal Radiometer Experiment on the International Space Station (ISS) has been used to generate three high-level products: evapotranspiration, water use efficiency, and the evaporative stress index — all focusing on how plants use water. -

The Tibetan Plateau (TP), known as Asia’s water tower, is quite sensitive to climate change, which is reflected by changes in hydrologic state variables such as lake water storage. Given the extremely limited ground observations on the TP due to the harsh environment and complex terrain, we exploited multiple altimetric mis- sions and Landsat satellite data to create high-temporal-resolution lake water level and storage change time series at weekly to monthly timescales for 52 large lakes (50 lakes larger than 150 km2 and 2 lakes larger than 100 km2) on the TP during 2000–2017. The data sets are available online at https://doi.org/10.1594/PANGAEA.898411 (Li et al., 2019). With Landsat archives and altimetry data, we developed water levels from lake shoreline posi- tions (i.e., Landsat-derived water levels) that cover the study period and serve as an ideal reference for merging multisource lake water levels with systematic biases being removed. -

On the Use of Scatterometer Winds in Nwp
ON THE USE OF SCATTEROMETER WINDS IN NWP Ad Stoffelen KNMI, de Bilt, the Netherlands, Email: [email protected] Lars Isaksen, Didier le Meur ECMWF, Reading, UK ABSTRACT Over the last years the processing of ERS scatterometer winds has been refined. Subsequently, High Resolution Limited Area Model, HIRLAM, and ECMWF model data assimilation experiments have been carried out to assess the impact of one scatterometer, ERS-1 and of two scatterometers, ERS-1 and ERS-2, on the analyses and forecasts. We found that scatterometer winds have a clear and beneficial impact in the data assimilation cycle and on the forecasts. Furthermore, ECMWF has shown that ERS scatterometer data improve the prediction of tropical cyclones in 4Dvar, where unprecedented skillful medium-range forecasts result of potential large social-economic value. Nevertheless, scatterometer winds contain much sub-synoptic scale information where the smallest scales resolved are difficult to assimilate into a Numerical Weather Prediction, NWP, model. This is mainly due to the otherwise general sparsity of the observing system over the ocean. In line with this it is found that scatterometer data coverage is very important for obtaining a large impact. In that respect future scatterometer systems such as SeaWinds on QuikSCAT and ADEOS- II, and ASCAT on EPS are promising. 1. INTRODUCTION After the launch of ERS-1 much improvement has been made in the interpretation of scatterometer backscatter measurements and a good quality wind product has emerged (Stoffelen and Anderson, 1997a, 1997b and 1997c). The consistency of the scatterometer winds over the swath makes them particularly useful for nowcasting purposes and several examples of the usefulness of the direct visual presentation of scatterometer winds to a meteorologist can be given. -
GST Responses to “Questions to Inform Development of the National Plan”
GST Responses to “Questions to Inform Development of the National Plan” Name (optional): Dr. Darrel Williams Position (optional): Chief Scientist, (240) 542-1106; [email protected] Institution (optional): Global Science & Technology, Inc. Greenbelt, Maryland 20770 Global Science & Technology, Inc. (GST) is pleased to provide the following answers as a contribution towards OSTP’s effort to develop a national plan for civil Earth observations. In our response we provide information to support three main themes: 1. There is strong science need for high temporal resolution of moderate spatial resolution satellite earth observation that can be achieved with cost effective, innovative new approaches. 2. Operational programs need to be designed to obtain sustained climate data records. Continuity of Earth observations can be achieved through more efficient and economical means. 3. We need programs to address the integration of remotely sensed data with in situ data. GST has carefully considered these important national Earth observation issues over the past few years and has submitted the following RFI responses: The USGS RFI on Landsat Data Continuity Concepts (April 2012), NASA’s Sustainable Land Imaging Architecture RFI (September 2013), and This USGEO RFI (November 2013) relative to OSTP’s efforts to develop a national plan for civil Earth observations. In addition to the above RFI responses, GST led the development of a mature, fully compliant flight mission concept in response to NASA’s Earth Venture-2 RFP in September 2011. Our capacity to address these critical national issues resides in GST’s considerable bench strength in Earth science understanding (Drs. Darrel Williams, DeWayne Cecil, Samuel Goward, and Dixon Butler) and in NASA systems engineering and senior management oversight (Drs. -
