'''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 250 m, 5 bands at 500 m and 29 bands at 1 km). 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.
