Abstract
Diplomska naloga najprej predstavi definicije in razlage osnovnih pojmov pri procesu evapotranspiracije in natančneje Penman–Monteithovo metodo za izračun le-te. V nalogi je predstavljen izračun referenčne evapotranspiracije z uporabo Penman–Monteith-ove enačbe za območje merilne meteorološke postaje Ljubljana-Bežigrad. Izračun ET0 smo naredili na več možnih načinov, kot so izračuni z različnimi časovnimi koraki podatkov (urni, dnevni, desetdnevni, mesečni) in izračuni za primere, ko nimamo na voljo vseh potrebnih meteoroloških podatkov. Med izračuni z uporabo različnih časovnih korakov (dnevni, desetdnevni, mesečni), ne prihaja do bistvenih razlik. Pri načinu izračuna, ko uporabimo alternativne načine izračuna evapotranspiracije, ko nimamo na voljo vseh potrebnih vhodnih podatkov, pa lahko s pravilno izbiro metod izračuna dobimo zadovoljive rezultate.

Title:Calculation of evapotranspiration using the Penman-Monteith equation
Abstract:
This thesis is presenting the most important facts in the process of evapotranspiration, with some definitions and Penman–Montetith equation, which is a standard equation for evapotranspiration calculation. In this work a calculation of reference evapotranspiration is presented, using Penman–Monteith equation, for Ljubljana-Bežigrad meteorological station. Several calculation procedures are presented, such as calculation using diffrent time steps of the data (hourly, daily, ten days, monthly) and calculation in case of missing climatic data. During calculations using different time steps (daily, ten-days, monthly), no significant differences were found. When using various calculation methods for calculating evapotranspiration in case of missing data, the correct choice of calculation methods can give satisfactory results.

Keywords:Evapotranspiration, evaporation, transpiration, Penman–Monteith equation, solar radiation, air temperature, air humidity, wind speed
