Evapotranspiração da cana-de-açúcar na região do Recôncavo Bahiano

Radiation fluxes over a surface close to a farm in Jaguaripe-BA were measured on clear day. The Bowen ratio method for calculating latent heat e 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 in the range 0 – 1, and the latent heat flux accounted the range 70 – 80% of the net radiation.
