| Description | A new approach of the estimation of erythemally effective ultraviolet (EUV) radiation for all sky conditions that could happen in maritime Antarctica is reported. Spatial variability of total ozone content and attenuation of EUV radiation in the atmosphere is taken into a consideration. The proposed nonlinear regression model of EUV radiation is described by a hyperbolic transmission function. The first results and the model validation for Vernadsky Station (formerly the British Faraday Station) within the period of 2002_2005 showed very good agreement with the measured values (R2=99.2). The developed model was evaluated using daily doses of EUV radiation with respect to solar elevation angle and cloudiness. Three categories of the cloudiness conditions were distinguished for the purpose of model verification. |
