The Moderate Resolution Imaging Spectrometer (Modis) observing facility on the Earth Observing System (EOS) is composed of two instruments: Modis-Nadir (N) and Modis-Tilt (T). Modis-N has 36 spectral bands between 0.4 and 14.2 microns, with spatial resolution between 250 and 1000 meters. Modis-T has 32 bands with 10-15 nm bandwidths between 0.4 and 0.9 microns. Modis-T scans fore and aft +/- 50 degrees. Both instruments scan cross-track so as to provide daily (Modis-N) or once every two days (Modis-T) coverage at 705-km altitude. Both instruments are entering into the execution phases of their development in 1990. The bands of the Modis-N hve been chosen so as to provide key observations of land, ocean, and atmosphere parameters that will provide key data sets assisting in gaining an improved understanding of global processes.
