Radiometric calibration of the Coastal Zone Color Scanner on Nimbus 7: a proposed adjustment.
Ground measurements of water reflectances for two very clear days, allied with computations of atmospheric effects, are compared with satellite data of the Coastal Zone Color Scanner. This exercise points out significant errors in the calibration of the scanner. A new set of calibration constants, which standardizes radiances relative to the extraterrestrial solar irradiance, is proposed.
