CEOS Instrument: Scanner for Earth's Radiation Budget




Instrument:ScaRaB
Agency: CNES
Missions: Meteor-3 N7
 Resurs-01 N4
 MEGHA-TROPIQUES
Status:Operational
Type:Broad-band radiometer
Description:Measures top-of-atmosphere shortwave radiation (0.2 - 4.0 Ám) and total radiation (0.2 - 50 Ám). Two additional narrow-band channels (0.5 - 0.7 Ám and 11 - 12 Ám) allow cloud detection and scene identification
Spatial Resolution: 40 km
Swath Width: 2200 km
Wavebands: VIS window channel: 0.5 - 0.7 ?m, Solar channel UV - SWIR: 0.2 - 4 ?m, Total channel UV - FIR: 0.2 - 50 ?m, Thermal window channel: 10.5 - 12.5 ?m
Technology: Broad-band radiometer
Description: Radiometer with channels that integrate the total radiation emerging from TOA (0.2-100 Ám) and the fraction of reflected solar radiation (0.2-4.0 Ám). Ancillary channels in atmospheric windows may be present. Capability of observing under more viewing directions so as to help converting radiances into irradiances may be present. Resolution in the range of 20-50 km. Applicable in LEO and GEO.
