- Based on 53 years of daily meteorological data from 1961 to 2013 provided by 19 meteorological stations in Hebei Provence, seven algorithms of Penman-Monteith (P-M), Hargreaves-Samani (H-S), Irmark-Allen (I-A), Pristley-Taylor (P-T), Makkink (M-K), Penman-Van Bavel (PVB), 1948 Penman(48-PM) were used to calculate daily ET0 of 3 areas in Hebei Provence. P-M was used as a standard to be compared with other 6 algorithms for estimating ET0. The 6 algorithms were compared from the goodness-of-fit, definition and the applicability of monthly average ET0 accumulated values. The algorithms got its scores after each comparative respects. The results show: I-A did the best work, scoring 23 points, and 48-PM ranked second, 11 points; these 2 methods can be the simplified recommendation to calculate ET0 in Hebei Provence. The study proves that it is reasonable to value the applicability of each equation by the scoring method.
