WGEN is a stochastic weather generator originally developed in the 1980s in Fortran at the US Department of Agriculture Agricultural Research Service (Richardson and Wright 1984). It uses monthly and annual statistics to generate daily time series of precipitation, minimum temperature, maximum temperature, and solar radiation.
Use the WGEN PAR model to generate the parameter inputs for this model. The inputs are saved in an Excel spreadsheet file called "WGEN PAR.xlsx" so please make sure that file is saved in the same directory as
