Comparison of the Results of Spectrally Integrated Irradiance Generated by Radiative Transfer ModelsSBDART and TUV

摘要

The present study aims to promote an evaluation of the differences in the results of integrated irradiance generated by two different Radiative Transfer codes: SBDART (Santa Barbara DISORT Atmospheric Radiative Transfer) and TUV (Tropospheric Ultraviolet and Visible), under similar conditions. The effect of different atmospheric profiles, values of the total ozone column and solar zenith angle (SZA) was evaluated. For the ultraviolet band, it was possible to observe smaller differences when the SZA was 80 degrees. In the visible band, the opposite was verified. Varying the integrated value of the ozone column, it was observed average differences of 7.75% in the ultraviolet band and 0.8% in the visible one. Different atmospheric thermodynamic profiles also produced differences around 7% in the ultraviolet and 1% in the visible band. Top of atmosphere solar irradiance (for varying SZA) show differences below 1% for both bands.
