[Q] How to generate daily weather data

 

Question

Can someone tell me how to generate daily weather data from an historical daily meteorological data set using WeatherMan in DSSAT)?

 

Answer

In order to generate daily weather data you require climate data as input. WeatherMan has the capability to create the climate data if you import at least 5 to 10 years of daily weather data. Once you have created the climate data file with WeatherMan, there is a separate option to generate daily weather data and then to export the files. In DSSAT you need to select externally generated weather data in the simulation controls in order for the model to find the data. Alternatively the Cropping System Model (CSM) of DSSAT can generate the weather data internally using the WGEN weather generator (W option in simulation controls) or the SIMMETEO weather generator (S option in simulation controls).
