3. WMO OMM 6th GOES Users' Conference, Madison, Wisconsin, Nov 3-5 3 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. 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. 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. 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
