|The results of the first year of measurements of the intensity of total ultraviolet and erythemally effective UVB radiation at two Antarctic stations are presented. The radiation data were collected within the period of 2005-2006 at the Czech Mendel Station, James Ross Island and Ukrainian Vernadsky Station, Galindez Island, Argentine Islands. The impact of stratospheric ozone concentration, cloud types and cloudiness on incident UV were examined. The effects of these factors were evaluated by (1) linear regression model, and (2) correlation analysis. The model outputs confirmed the different influence of the above-specified independent variables on UV radiation. The most significant factor was cloudiness and cloud types. The obtained findings confirmed an assumption of the different influence of the analyzed factors between western and eastern coast of the Antarctic Peninsula.
