The video is updated once per day.  \r\n\r\nSpacecraft included:\r\n• Aqua\r\n• Aura\r\n• CALIPSO: Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation\r\n• CYGNSS-1: Cyclone Global Navigation Satellite System 1\r\n• CYGNSS-2: Cyclone Global Navigation Satellite System 2\r\n• CYGNSS-3: Cyclone Global Navigation Satellite System 3\r\n• CYGNSS-4: Cyclone Global Navigation Satellite System 4\r\n• CYNGSS-5: Cyclone Global Navigation Satellite System 5\r\n• CYGNSS-7: Cyclone Global Navigation Satellite System 7\r\n• CYGNSS-8: Cyclone Global Navigation Satellite System 8\r\n• Cloudsat\r\n• GPM: Global Precipitation Measurement\r\n• GRACE-FO-1: Gravity Recovery and Climate Experiment Follow On-1\r\n• GRACE-FO-2: Gravity Recovery and Climate Experiment Follow On-2\r\n• ICESat-2\r\n• ISS: International Space Station\r\n• Landsat 8\r\n• Landsat 9\r\n• OCO-2: Orbiting Carbon Observatory-2\r\n• SMAP: Soil Moisture Passive Active\r\n• Suomi NPP: Suomi National Polar-orbiting Partnership\r\n• Sentinel-6 Michael Freilich\r\n• SWOT\r\n• Terra\r\n\r\nThe clouds used in this version are from a high resolution GEOS model run at 10 minute time steps interpolated down to the per-frame level. The timeframe for this model does not match the date in this fleet visualization, so the clouds shown do not represent actual conditions for today.",
