Earth-Observing Instruments on Aqua
• Atmospheric Infrared Sounder (AIRS)• Advanced Microwave Sounding Unit (AMSU)• Humidity Sounder for Brazil (HSB)• Moderate Resolution
Imaging Spectro- radiometer (MODIS)
• Clouds and the Earth’s Radiant Energy System (CERES; two instruments)
• Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E)
Methods of Sending the Aqua Data to the Ground
• Direct playback from the solid state recorder (SSR), while in view of one of the EOS Polar Ground Stations.
• Direct broadcast, to anyone with a receiving system.
Direct Playback (150 Mbps) or
Direct Broadcast (10 Mbps)X-band Direct B
roadcast (10 M
bps)
