AbstractAccurate determination of atmospheric effects is crucial to earth-based inflight radiometric calibration of existing satellite systems. Such calibration work relies on computer codes which compute atmospheric transmittance due to both scattering and absorption processes. Two solar radiometers were used for atmospheric data collection. Results obtained from the two instruments in the visible are compared. Modifications to the autotracking instrument are discussed. The accuracy of existing methods for determining the amounts of key atmospheric constituents actually present at a given time is examined. Computation of integrated water vapor content based on solar radiometer data is discussed. Calculations to account for the effects of gaseous absorption in the near infrared spectral bands of a solar radiometer are outlined. Such corrections will facilitate calibration of these spectral bands. In conclusion, the effects of the uncertainties in the current determination of crucial atmospheric parameters on radiance at the satellite level are examined.
