Solar UV irradiance measurements in Antarctica are often carried out by automatic or semiautomatic equipment. The unattended way of managing instruments needs accurate knowledge of the parameters affecting experimental data, among which cloudiness plays a fundamental role. A moderate-band multifilter radiometer and a total sky camera were installed for a test in the Italian Antarctic base (Terra Nova Bay, 74.07°S, 164.08°E) during the summer campaign 2002 - 2003. This paper shows preliminary results on the radiometer spectral data and a comparison with modelled spectral irradiances. Moreover, the radiometer integrated irradiance, computed by means of a new model, was compared with the updated Green model integrated irradiance, corrected by a cloud factor obtained from the sky camera images. Results showed good agreement on the integrated irradiances but poor results, except for 305 nm, when spectral values were analyzed.
