Satellite missions in the Vision for the GOS in
2025
Heritage operational missions

• 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

Permanent watch from GEO orbit

• 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

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)

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
