In this paper, temporal trend of annual reference evapotranspiration (ET0) calculated using the FAO Penman-Monteith equation with the observed daily meteorological data at six stations (i.e. Datong, Weichang, Qinhuangdao, Tianjin, Beijing and Huimin) of Haihe River Basin, China, were detected with the help of parametric t-test and Mann-Kendall (MK) analysis. The six stations were divided in three...
Teten, Buck and Magnus formulas for saturation vapor pressure es calculation were evaluated under different temperature conditions, compared with Goff-Gratch formula. Then errors of vapor pressure deficit VPD and reference crop evapotranspiration ET0 derived from es by Teten were examined in high latitude cold regions. Error of es by Teten increased linearly with reduction of temperature. When it...
