Blaney–Criddle equation : ウィキペディア英語版 | Blaney–Criddle equation The Blaney–Criddle equation (named after H. F. Blaney and W. D. Criddle) is a method for estimating reference crop evapotranspiration. == Usage == The Blaney–Criddle equation is a relatively simplistic method for calculating evapotranspiration. When sufficient meteorological data is available the Penman–Monteith equation is usually preferred. The Blaney–Criddle equation is however ideal when only air temperature data is available for a site. Given the coarse accuracy of the Blaney–Criddle equation it is recommended that it is used to calculate evapotranspiration for periods of one month or greater (). The equation calculates evapotranspiration for a 'reference crop', which is taken as actively growing green grass of 8–15 cm height ().
