Sažetak
This paper is a presentation of erythemally effective irradiance measurements carried out in Zagreb, Croatia. The amounts of UV irradiance are expressed as erythemally effective dosages in MED/h, where one MED equals 250 Jm^-2. The paper presents the results obtained in May 1999. The maximal and minimal noontime means of erythemally ef fective irradiance were 3.149 MED/h and 0.508 MED/h, respectively. The daily course in clear sky conditions has a bell-shape distribution. For cloudy sky, the daily course curve is asymmetrical with reduced amounts of erythemally effective dosages. Simultaneous measurements of global irradiation and relative humidity were used to examine their connection with erythemally effective dosages. The simple linear regression method has shown that the relationship between erythemally effective dosages (predictand) and global radiation (predictor) gives better results than the same method with relative humidity as a predictand. On the other hand, the highest value of the correlation coefficient was obtained by multiple linear regression including both predictors. However, the improvement was not significant compared to the results obtained by simple linear regression with global radiation as the only predictand.
