Current Research in Agricultural Sciences, 2020 Various methods are available to predict reference evapotranspiration (ETo) but the Penman-Monteith (PM) ETo method has been considered to be the most accurate ETo method to determine ETo. The PM ETo method can be solved by various weather parameters like atmospheric temperature, wind velocity, moisture content and net solar radiations.

Alexandria Engineering Journal, 2013 There are many empirical and theoretical equations to estimate the value of the potential evapo-transpiration (PET) under certain weather conditions. The relation between PET and climatic factors has the greatest role in the development of such equations.

Erratum to: Evaluation and calibration of Blaney–Criddle equation for estimating reference evapotranspiration in semiarid and arid regions [PDF]
Environmental Earth Sciences, 2015 Penman–Monteith (FAO-56 PM) equation is suggested as the standard method for estimating evapotranspiration by the International Irrigation and Drainage Committee and FAO. On the other hand, the Blaney–Criddle (BC) temperature-based equation is an alternative and simple method compared with the FAO-56 PM equation.

Ecosphere, Volume 11, Issue 8, August 2020., 2020 Abstract Peak snowpack in the western USA has decreased 21% since the mid‐20th century, and these trends are forecasted to continue over the next century. In water‐limited systems, forest productivity during the growing season is assumed to be linked with snowpack during the previous winter, but this linkage has proven not to be universal in studies ...

Historical Rainfall and Evapotranspiration Changes over Mpologoma Catchment in Uganda
Advances in Meteorology, Volume 2020, Issue 1, 2020., 2020 Changes in the long‐term (1948–2016) rainfall and evapotranspiration over Mpologoma catchment were analysed using gridded (0.25° × 0.25°) Princeton Global Forcing data. Trend and variability were assessed using a nonparametric approach based on the cumulative sum of the difference between exceedance and nonexceedance counts of data.
