Moderate resolution imaging spectrometer‐tilt (modis‐t)

摘要

AbstractThe Moderate Resolution Imaging Spectrometer‐Tilt (MODIS‐T) instrument is being constructed for flight on the Earth Observing System (EOS). It is an imaging spectrometer utilizing a grating‐type, reflecting Schmidt optical design that must provide a 1.1‐km spatial resolution at nadir from a spacecraft altitude of 705 km with a 1500‐km cross‐track swath and a ±50° fore and aft tilt capability. The instrument is required to cover the wavelength range from 400 to 880 nm in approximately 15‐nm steps with less than 2.3 instrument‐induced polarization. The absolute radiometric accuracy must be at least 5 over the full dynamic range
