Abstract

The intensity of erythemally effective UVB radiation at the Earth's surface is mainly affected by solar zenith angle, Earth-Sun distance, ozone amount, cloudiness and clouds genera, aerosol content in the atmosphere, and surface albedo. In contrast to geometric factors of the Sun and sunrays, the influence of the ozone and clouds on the incident UV radiation is not satisfactorily explained. Furthemore, the effects of both factors are complement and negative correlated with the UV radiation. It means the resultant values of erythemally effective UVB irradiation (E-UVB) may not correlate with total ozone column in some cases. Moreover, the increase of the solar zenith angle causes the rise of effective ozone column at the same time. In this contribution we have analysed influence of the above-mentioned factors on E-UVB radiation at Mendel station and Vernadsky station by using nonlinear regression model. The model results were evaluated for different sources of total ozone column (sattellite, ground-based measurement) on E-UVB radiation time series.

Abstract (in Czech)

Intenzita erytemálně aktivního UVB záření na zemském povrchu závisí na řadě faktorů, mj. na množství ozónu v atmosféře a na oblačnosti. Tato závislost není dosud zcela uspokojivě vysvětlena. Příspěvek se zabývá popisem této závislosti pomocí nelineárního regresního modelu s využitím dat ze dvou antarktických stanic, a to české stanice J.G. Mendel a ukrajinské stanice Vernadsky.
