2 6th GOES Users' Conference, Madison, Wisconsin, Nov 3-5 The space-based Global Observing System Vision for 2025

WMO OMM 6th GOES Users' Conference, Madison, Wisconsin, Nov Satellite missions in the Vision for the GOS in 2025Vision for the GOS in 2025 Transition from R&D to operational status New missions for WMO  GEO: imager, HS IR sounder, lightning  Sun-synchronous: imager, IR/MW sounders  Ocean surface topography constellation  Radio-Occultation Sounding constellation  Ocean Surface Wind constellation  Global Precipitation constellation  Earth Radiation Budget (incl. GEO)  Atmospheric Composition (incl. GEO)  Ocean colour and vegetation imaging  Dual-angle view IR imagery  Land Surface Imaging  Synthetic Aperture Radar  Space Weather instruments  VIS/IR imagers in HEO  Doppler wind lidar, Low-frequency MW  GEO MW  High-resolution narrow-band imagers  Gravimetric sensors Heritage operational missions Operational pathfinders and demonstrators

4 6th GOES Users' Conference, Madison, Wisconsin, Nov 3-5 Rapidly evolving weather patterns –Convection /severe storms / hurricanes –Targeted observation Wind –Clouds and water vapour motion tracking Event detection –Lightning, wild fires –Volcanic ash clouds Diurnal variation –LST, SST, Radiation –Peak values (air quality) Maximize cloud-free pixels Permanent watch from GEO orbit

5 6th GOES Users' Conference, Madison, Wisconsin, Nov 3-5 High-latitude coverage by HEO satellites Supplementing the GEO coverage above 60/70 deg  Winds and clouds (rapidly developing polar lows)  Sea ice and sea surface temperature  Volcanic ash plumes (For NWP, synoptic weather forecasting, aeronautical meteorology, marine meteorology, climate monitoring, Global Cryosphere Watch) Recommended demonstration (operational pathfinder) Compare cost/benefit with LEO constellation Synergy with other missions in HEO (telecom)

6 6th GOES Users' Conference, Madison, Wisconsin, Nov 3-5 Challenges and opportunities Geostationary operational missions –IR hyperspectral sounding on every operational GEO  Near-global lightning detection (GOES, Meteosat, FY-4)  GEO microwave imager/sounder for precipitation rate Operational pathfinders in HEO  Scientific and operational cooperation –Sustainability to be confirmed Integration of GEO, LEO (and HEO) observations –Intercalibration –Data standardization –Composite products
