Prediction of erythemally effective UVB radiation by means of nonlinear regression model

Abstract

AbstractOne of the research programs carried out within the Czech‐Ukrainian scientific co‐operation is the monitoring of global solar and ultraviolet radiation at the Vernadsky Station (formerly the British Faraday Station), Antarctica. Radiation measurements have been made since 2002. Recently, a special attention is devoted to the measurements of the erythemally effective UVB radiation using a broadband Robertson Berger 501 UV‐Biometer (Solar Light Co. Inc., USA). This paper brings some results from modelling the daily sums of erythemally effective UVB radiation intensity in relation to the total ozone content (TOC) in atmosphere and surface intensity of the global solar radiation. Differences between the satellite‐ and ground‐based measurements of the TOC at the Vernadsky Station are taken into consideration. The modelled erythemally effective UVB radiation differed slightly depending on the seasons and sources of the TOC. The model relative prediction error for ground‐ and satellite‐based measurements varied between 9.5% and 9.6% in the period of 2002–2003, while it ranged from 7.4% to 8.8% in the period of 2003–2004.
