Paper Abstract

Mean daily values of the total atmospheric optical depth have been obtained from measurements of spectral solar irradiance at ground level in Valencia, Spain. These measurements have been taken during ten days in the years 1993 and 1994. The total columnar ozone amount and aerosol optical depths have been calculated using both King and Byrne and by Flittner at al. methods. The results obtained show that these algorithms lead to big errors if they are employed to determine instantaneous values of total ozone content. If they are used to calculate mean daily values, both methods give similar results either for the total ozone content or the aerosol optical depth, with quite acceptable errors. Considering the errors introduced by any one of the two methods, King's algorithm leads to higher imprecision in the aerosol optical depth determinations. This imprecision is particularly significant when the curve of the aerosol optical depth as a function of wavelength differs from the exponential law proposed by Angstrom.
