Abstract: In this article, the relation of evaporation deriving meteorological parameters particularly wind speed, solar radiation and vapor pressure deficit with evaporation schemes namely Class A pan evaporation (Ep), potential evapotranspiration (PET) and reference evapotranspiration (ETo) at Tharandt, Germany for the years from 2004 to 2013 was investigated. PET was calculated using three methods: 1. Haude (2005), 2. Wendling (1991), 3. Penman (1963); whereas, ETo was calculated according to Food and Agricultural Organization-Penman Monteith method. The results showed that the evaporatin schemes were mainly driven by solar radiation (R2 ≥ 0.69, RMSE ≤ 0.76mm d-1) and vapor pressure deficit (R2 ≥ 0.53, RMSE ≤ 0.92mm d-1).
