'''MODIS''' ('''Moderate-resolution Imaging Spectroradiometer''') is a [[payload]] scientific instrument launched into [[Earth]] [[orbit]] by [[NASA]] in [[1999]] on board the [[Terra (satellite)|Terra]] (EOS AM) Satellite, and in [[2002]] on board the [[Aqua (satellite)|Aqua]] (EOS PM) satellite. The instruments capture data in 36 spectral bands ranging in wavelength from 0.4 µm to 14.4 µm and at varying spatial resolutions (2 bands @at 250m250 m, 5 bands @at 500m500 m and 29 bands @at 1 1kmkm). Together the instruments image the entire earth every 1 to 2 days. They are designed to provide measurements in large-scale global dynamics including changes in Earth's [[cloud]] cover, [[radiation budget]] and processes occurring in the oceans, on land, and in the lower atmosphere.
