Measurements and Applications
|
Takes pictures of atmospheric band emissions from below the satellite. This provides complementary information on smaller spatial scales, albeit restricted to a single spectral channel. Because of the nadir instruments susceptibility to the background light of the lower atmosphere, the nadir imaging will be restricted to the night-side of the terminator. The nadir instrument is basically a wide-angle camera.
