Estimativa de balanço de energia na região do Curaçá

Radiation fluxes over a surface close to Sobradinho Dam, were measured on clear day. The Bowen ratio method for calculating latent heat and sensible heat fluxes density was used by measuring temperature and water vapour at two heights. Each of energy fluxes density was computed from the Bowen ratio and net radiation minus soil heat fluxes density. The site of interest, under drought conditions, the Bowen ratio was usually in the range 1 – 3, and the latent heat flux accounted for only 15% of the net radiation.
