Název v původním jazyce

Estimation of Erythemally Effective UVB Radiation at Two Antarctic Stations

Popis výsledku v původním jazyce

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 theresultant 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 contributionwe have analysed influence of the above-mentioned factors on E-UVB radiation at Mendel station and Vernadsky station by using nonlinear regression model.
