About Aqua
Images and data

The EOS Data and Information System (EOSDIS) provides the total ground system for processing, archiving, and distributing science and engineering data from all the EOS spacecraft, including Aqua. Earth Science Mission Operations (ESMO) provides the mission operations systems that perform the functions of command and control of the spacecraft and instruments, health and safety monitoring, mission planning and scheduling, initial data capture, and Level 0 processing. Command of all the EOS spacecraft and instruments is done at the EOS Operations Center located at NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland.

direct broadcast

On July 12, 2002, Aqua began broadcasting all of its instrument data (AIRS/AMSU-A/HSB, AMSR-E, CERES, and MODIS) on X-Band. With more extensive filtering capability on its transponder, Aqua is broadcasting almost all the time except during the ground contact time over the Poker Flat, Alaska, and Svalbard, Norway. Interruption lasts about 5 minutes, once per orbit. [Aqua's sister satellite, Terra, began broadcasting selected portions of MODIS instrument data on X-Band on March 17, 2000. The broadcast is continuous with following exceptions: 1. During the time Aqua is dumping its play-back data which lasts about 15 minutes, once per orbit; 2. When the spacecraft is in the line-of-sight of NASA Deep Space Stations (Goldstone, Canberra, and Madrid)].

Anyone interested in obtaining direct broadcast data or establishing a downlink site should refer to the EOS Direct Broadcast Website.

MODIS Data image   MODIS Level 1 data, geolocation, cloud mask, and atmosphere products can be found on the LAADS Web and MODIS ocean color and sea surface temperature products can be found on the Ocean Color Web. Land data are stored and distributed by the Land Processes Distributed Active Archive Center, and snow and ice data are stored and distributed by NSIDC.
