CEOS EO HANDBOOK – INSTRUMENT SUMMARY - ScaRaB -
Full Name Scanner for Earth's Radiation Budget Status Operational
Instrument Agencies CNES Maturity
Instrument Type Earth radiation budget radiometers Geometry Cross-track scanning
Instrument Technology Broad-band radiometer Sampling Imaging
Data Access Constrained 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.
