This is the GoldSim implementation of the WGEN PAR Program originally written by Dee Allen Wright in 1983. The FORTRAN IV source code was translated directly to GoldSim with a couple of differences(1). The purpose of the model is to generate rainfall and other climate generation parameters that are needed to run WGEN. Enter time series data for rainfall, min and max temperature, and radiation (found in the file called "WGEN PAR TS.xlsx" located in the same directory of the model). Run the model from the start time that the time series data begins and end time that the time series data ends. After the model runs, it will automatically export the parameters to an Excel file named "WGEN PAR.xlsx".
