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 micrometers with spatial resolution between 214 and 856 meters. MODIS-T has 32 bands with 10-15 nanometer bandwidths between 0.4 and 0.9 micrometers. MODIS-T scans fore and aft + or - 50 degrees. Both instruments scan cross-track so as to provide daily (MODIS-N) or once every 2 days (MODIS-T) coverage at 705 kilometers altitude. Both instruments are entering into the execution phases of their development in 1990.
