In this paper, results of certain empirical equations for estimating the daily reference evapotranspiration for the area of southern Italy have been given. Evaluation of the daily values of evapotranspiration of Policoro was conducted by the following equations: FAO-56Penman-Monteith (FAOPM), FAO-24 Penman (FAOPn), FAO-24 Blaney-Criddle (FAOBC), FAO-24 Radiation (FAOR), FAO-24 Pan, Priestley-Tailor (PT) and Hargreaves (HARG). The results strongly support the use of the FAO-24 pan and FAO-56 Penman-Monteith equations for the calculation of daily reference evapotranspiration at the location of Policoro.
Key words:
Reference evapotranspiration; Penman-Monteith; Class A pan, Policoro
POREDJENJE EMPIRIJSKIH JEDNAČINA ZA PRORAČUN DNEVNIH VREDNOSTI REFERENTNE EVAPOTRANSPIRACIJE
U ovom radu predstavljeni su rezultati pojedinih empirijskih jednčina za proračun dnevnih vrednosti referentne evapotranspiracije na području Polocoro, Italija i to: FAO-56 Penman-Monteith (FAOPM), FAO-24 Penman (FAOPn), FAO-24 Blaney-Criddle (FAOBC), FAO-24 Radiation (FAOR), FAO-24 Pan, Priestley-Tailor (PT) and Hargreaves (HARG). Dobijeni rezultati snažno podržavaju korišćenje FAO-24 Pan i FAO-56 Penman-Monteith jednačina za računanje dnevnih vrednosti referentne evapotranspiracije na lokaciji Policoro, Italija.
Ključne reči:
Reference evapotranspiration; Penman-Monteith; Class A pan, Policoro
