Abstract: Measurements of solar UV-B radiation in the biological band (280 nm 320 nm) with the help of ground based UV-B Photometer at VISAKHAPATNAM (17.70 N, 83.30 E) have been used to develop a simple regression model. The model was developed with measured values of incoming UV-B radiation obtained by UV-B photometer deployed in the Department of Physics, Andhra University (1989-1993) and satellite measured column ozone as inputs. The model is useful to find unknown values by providing known inputs. Hence satellite measured values of columnar ozone for the period 2005-2013 were provided as one input, solar zenith angle as another input and incoming UV-B radiation for this period was estimated. With the estimated values of incoming solar UV- B radiation an attempt was made to analyze the dependence of incoming solar UV-B radiation on columnar ozone and also its dependence on solar zenith angle and wavelength.
