NIMBUS-7

The objectives of NIMBUS-7 ERB are 1) to obtain accurate measurements of solar irradiance, monitor its variation in time, and observe the temporal variation of the solar spectrum: and 2) to determine the Earth radiation budget from simultaneous measurements of the incoming solar radiation and the outgoing Earth-reflected and Earth-emitted radiation. The SEFDT contains calibration optimized wide-field-of-view (121 degrees unencumbered FOV) Earth irradiances (at satellite altitude) and solar channel (extraterrestrial solar irradiation) data. The latitude and longitude of the Earth pixels are given. The solar channel data are restricted to the vicinity of the Sun-viewing period of the orbit. Both raw counts and calibrated radiances and irradiances are given. Filter degradation in the narrow spectral band solar channels has not been corrected.
