AbstractThis paper describes statistical and climatic analyses of G, UV, PAR and NIR irradiations, and UV/G, PAR/G and NIR/G fractions using a data base obtained from 2001 to 2005 in Botucatu/SP/Brazil. Values of irradiations and fractions are presented in two systematic series: Diurnal and Annual. Diurnal series shows values of irradiations and hourly mean fractions in annual and monthly time intervals, while annual series shows values of irradiations and monthly mean (hourly and daily) fractions. Effects of clouds, water vapor and aerosols were analyzed and discussed in the seasonal variations of irradiations and fractions in both series
