Abstract

This paper reports a study about the diffuse, direct and global radiation levels on surface of earth, the irradiation over the top of atmosphere and the monthly relative sunstroke in the city of Cascavel, State of Paraná, southern Brazil. The solar radiation components were monitored from January, 2001 to February, 2003 at Estação Experimental Agrometeorológica of Unioeste, Cascavel, Parana State. Global radiation was monitored by a pyranometer KIPP & ZONEN CM3 and direct radiation was monitored by a pyrheliometer EPPLEY-NIP coupled to a solar tracer. The diffuse radiation was monitored through the difference between global and direct radiation. Monthly average levels of global, direct and diffuse irradiations were 51.8%, 31.7% and 20.17% of the irradiation in the top of atmosphere. The relative isolation index showed the maximum value in August (61.43%) and the minimum in February (34.35%). These periods were characterized by clear and cloudy days, respectively, in the southern hemisphere
