Abstract

A continuing series of measurements of atmospheric radiances in the Hartley-Huggins bands of ozone absorption and corresponding solar irradiance measurements have been made since 1970 by a series of 0.25 meter focal length tandem Ebert-Fastie double monochromators. An ozone inversion algorithm yields profiles and total column amounts from the ratio of atmospheric radiances/solar irradiances at 12-wavelengths in the region 250-340nm. This work discusses major sources of uncertainties in the atmospheric reflectances which are used in the ozone inversion algorithm. A summary of SBUV type instrument calibration parameters are given in Table 1.
