CEOS Instrument: POLarization and Directionality of the Earth's Reflectances

Agencies: CNES [Primary]
Mission: ADEOS-II
Status:No longer operational
Type:Multi-channel/direction/polarisation radiometer
Description:Measures polarization, and directional and spectral characteristics of the solar light reflected by aerosols, clouds, oceans and land surfaces
Spatial Resolution: 6 x 7 km
Swath Width: 2400 (across track) x 1800 km (along track)
Wavebands: VIS - NIR: 0.443 ?m, 0.670 ?m and 0.865 ?m at 3 polarisations; and 0.443 ?m, 0.49 ?m, 0.565 ?m, 0.763 ?m, 0.765 ?m and 0.91 ?m with no polarisation
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.
