CEOS Instrument: Medium-Resolution Imaging Spectrometer




Instrument:MERIS
Agency: ESA
Mission: Envisat
Status:Operational
Type:Medium-resolution spectro-radiometer
Description:Main objective is monitoring marine biophysical and biochemical parameters. Secondary objectives are related to atmospheric properties such as cloud and water vapour and to vegetation conditions on land surfaces
Spatial Resolution: Ocean: 1040 x 1200 m, Land & coast: 260 x 300 m
Swath Width: 1150 km, global coverage every 3 days
Wavebands: VIS - NIR: 15 bands selectable across range: 0.4 - 1.05 ?m (bandwidth programmable between 0.0025 and 0.03 ?m)
Technology: Medium-resolution spectro-radiometer
Description: Used when the number of channels is high and they are too close to be separated by dichroics and filters. The instrument spreads the radiation beam by means of a spectrometer, but thereafter only a limited number of channels is selected, that generally is re-programmable. Channels bandwidths 1-3 %, spatial resolution typically 0.5-5 km. Applicable in LEO and GEO.
