| Abstract: | Potential evapotranspiration (E0), as an estimate of the evaporative demand of the atmosphere, has been widely discussed in researches on irrigation management, crop water demand and predictions in ungauged basins (PUBs). Analysis of the sensitivity of E0 to meteorological factors is the basic research on the impact of climate change on water resources, and also is important to the optimal allocation of agricultural water resources. In this study, the calculation method of global radiation in Penman-Monteit... |
