Earth Radiation Budget
Measurement of reflected and emitted terrestrial radiation fluxes in conjunction with solar radiation
22-channel radiometer. 10 channels in the range 0.2-5.0 μm to measure the incoming solar irradiance: 4 non-scanning wide-angle earth-viewing channels in the range 0.2-50 μm; and 8 scanning channels for multi-angle observation (4 in SW, 4 in LW)
Paving the way for the follow-on Earth Radiation Budget Experiment (ERBE)
Solar irradiance channels (10): sun pointing. Non-scanning earth-viewing channels (4): swath 3300 km. Scanning earth-viewing channels (8): biaxial, swath depending from the incidence angle, maximum 3300 km
Scanning channels: 80 km s.s.p.
