UV index forecasting in the Vojvodina region

Abstract

© 2019 RAD Association. All rights reserved. The UV index (UVI) values were calculated by an empirical model over Novi Sad (19.8 E, 45.3 N, 84 m), Vojvodina region, Serbia, on clear sky days in all seasons. The ground-based ozone measurements for this location, the solar zenith angles and the distance from the Sun were used as input data for the model. At the same site, the UVI values were measured by a Yankee Environmental Systems (YES) UVB-1 pyranometer. The measured values were compared to the calculated values. This comparison was performed to improve this model for UVI forecast in the Vojvodina region. The differences between the modeled and measured data are small enough with root-mean-square differences of less than 0.8 in summer and 0.3 in winter, so we can conclude that this model could be used for UVI forecast for clear sky conditions in this region.
