The MODerate Resolution Imaging Spectroradiometer (MODIS) is an imaging instrument flown onboard NASA's Earth Observing System (EOS) series of polar orbiting satellites. Scientists at SSEC are using MODIS data to advance understanding of the earth/atmosphere system, particularly through research on cloud detection, distribution, and composition; as well as retrieving atmospheric temperature and moisture.
SSEC has a direct broadcast downlink that receives MODIS data in real time. SSEC scientists have developed software (International MODIS/AIRS Processing Package (IMAPP)) to process direct broadcast data. IMAPP allows any ground station in the world capable of receiving direct broadcast from Terra or Aqua to produce calibrated and geolocated MODIS radiances (Level 1), along with a select group of science products (Level 2). IMAPP is derived from the operational MODIS processing software developed at NASA Goddard, and is modified to be compatible with direct broadcast data.
