CEOS EO HANDBOOK – INSTRUMENT SUMMARY - ScaRaB/MV2 -
Full Name Scanner for Earth's Radiation Budget Status No longer operational
Instrument Agencies CNES, NPO PLANETA Maturity
Instrument Type Earth radiation budget radiometers Geometry Cross-track scanning
Instrument Technology Broad-band radiometer Sampling Imaging
Data Access Data Format
Measurements and Applications Measures top-of-atmosphere shortwave radiation (0.2 - 4.0 µm) and total radiation (0.2 - 50 µm). Two additional narrow-band channels (0.5 - 0.7 µm and 11 - 12 µm) allow cloud detection and scene identification.
Resolution Summary 60 km
Swath Summary 2200 km
Accuracy Summary Absolute: ± 2.5 W/m2/sr, Relative: ± 0.7 W/m2/sr
Waveband Summary VIS window channel: 0.5 - 0.7 µm, Solar channel UV - SWIR: 0.2 - 4 µm, Total channel UV - FIR: 0.2 - 50 µm, Thermal window channel: 10.5 - 12.5 µm
UV (~0.01 µm - ~0.40 µm)
VIS (~0.40 µm - ~0.75 µm)
TIR (~6.0 µm - ~15.0 µm)
FIR (~15.0 µm - ~0.1 cm)
