MODIS

MODIS (Moderate Resolution Imaging Spectroradiometer) is as key instrument onboard the Terra and Aqua satellites as part of NASA's Earth Observing System (EOS).  MODIS provides 250m, 500m and 1000m imagery of the Earth in 36 spectral bands from 0.4 µm to 14.4 µm.  Between the two satellites the MODIS instruments can image the entire Earth every 1-2 days.  The MODIS instruments were designed to provide data on large-scale global dynamics in the oceans, on land and in the lower atmosphere.
