Summary
Description
MERIS is a programmable, medium-spectral resolution, imaging spectrometer operating in the solar reflective spectral range. Fifteen spectral bands can be selected by ground command. MERIS is designed so that it can acquire data over the Earth whenever illumination conditions are suitable. The instrument's 68.5\'b0 field of view around nadir covers a swath width of 1150 km. This wide field of view is shared between five identical optical modules arranged in a fan shape configuration. The instrument is capable of 300m resolution delivered via direct broadcast, but collects a reduced resolution (~1.2km) global coverage data set on-board the spacecraft. This product is the calibrated top-of-atmosphere radiances in the 15 spectral bands at this reduced resolution.
