CEOS Instrument: Sea-Viewing Wide Field-of-View Sensor




Instrument:SeaWiFS
Agencies: Orbital [Primary]
 NASA
Mission: OrbView-2
Status:No longer operational
Type:Medium-resolution spectro-radiometer
Description:Data on aerosols and ocean colour and biology. OrbView-2 is a commercial mission where NASA retains all rights to data for research purposes, while Orbital retains all rights for commercial and operational purposes.
Spatial Resolution: 1.1 km (local) and 4.4 km (global) at nadir
Swath Width: 1500 - 2800 km
Wavebands: VIS - NIR: 0.402 - 0.422 ?m, 0.433 - 0.453 ?m, 0.48 - 0.5 ?m, 0.5 - 0.52 ?m, 0.545 - 0.565 ?m, 0.66 - 0.68 ?m, 0.745 - 0.785 ?m and 0.845 - 0.885 ?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.
