CEOS Instrument: Along Track Scanning Radiometer - 2




Instrument:ATSR-2
Agencies: UKSA [Primary]
 CSIRO
Mission: ERS-2
Status:No longer operational
Type:Multi-channel/direction/polarisation radiometer
Description:Measurements of sea surface temperature, land surface temperature, cloud top temperature and cloud cover, aerosols, vegetation, atmospheric water vapour and liquid water content
Spatial Resolution: IR ocean channels: 1 x 1 km, Microwave near-nadir viewing: 20 km instantaneous field of view
Swath Width: 500 km
Wavebands: VIS - SWIR: 0.65 ?m, 0.85 ?m, 1.27 ?m, and 1.6 ?m, SWIR-TIR: 1.6 ?m, 3.7 ?m, 11 ?m and 12 ?m, Microwave: 23.8 GHz, 36.5 GHz (bandwidth of 400 MHz)
Technology: Multi-channel/direction/polarisation radiometer
Description: Imaging Vis/IR radiometer that addresses parameters observable by exploiting different viewing conditions (e.g., to convert radiances into irradiances), different polarisations (to reconstruct the electric field, i.e. the Stokes vector) and more channels (to collect more spectral signatures). A variety of configurations are possible. Multi-polarisation and multi-directionality are appropriate for short wavelengths. Channels bandwidths 2-5 %, spatial resolution typically 0.5-5 km. Applicable only in LEO.
