Its observed that: a) global solar radiation is maximum in ectober and minimum in July; b) relative global solar radiation is maximum in Au­gust and minimum in November c) sunshine duration is maximum in June and minimum in November; d) relative sunshine duration is maximun in June and mínimum in November. Correlation between the monthly of daily re1ative global solar radiation and of daily sunshine duration allo­wed to conclude that the linea􀂠 equation: Kg = KA (0,49 n/N) Were the letters are monthly means of: daily global radiation (ly/day) KA: daily solar radiation on the top of atmosphere (ly/day) n = daily duration of sunshine (hr/day) N daily maximum duration of sunshine (hr/day) lhe methodology adoted was the one proposed by PRES­tOT! (1940) and PENMAN (1948), as cited by 8LACK et alii {1954)􀃷 in arder to estimate parameters "a" and "b", in the equation Kg/KA = a + b 􀀬 Whick correlates the sunshine ratio (n/N) to the relative solar radiation (K9/KA) by linear regression analy -si s. The equation found s􀄮d a correlation coefficient wich was great that 0,95 with significance at 0,1 probabili ty level..porAcesso AbertoArtigo
