Analysis of erythemally effective UV radiation at the Mendel Station, James Ross Island in the period of 2006-2007

Popis výsledku v původním jazyce

The results of erythemally effective ultraviolet (EUV) radiation measurement at the J.G. Mendel Station are presented for the period of 2006-2007. The effects of stratospheric ozone concentration and cloudiness (estimated as cloud impact factor from global solar radiation) on the intensity of incident EUV radiation were calculated by a non-linear regression model. The total ozone content (TOC) and cloud/surface reflectivity derived from satellite-based measurements were applied into the model for elimination of the uncertainties in measured ozone values. The TOC data was acquired for the Mendel Station location from the EOS Aura OMI and V8.5 algorithm. Analysis of measured EUV data showed that variable cloudiness affected rather short-term fluctuationsof the radiation fluxes, while ozone declines caused long-term UV radiation increase in the second half of the year. The model predicted about 98 % variability of the measured EUV radiation.
