ABSTRACT DAILY weather data generated with a weather generation model (WGEN) were evaluated as a substitute for actual weather data as input to a selected crop model (CERES-Wheat). Wheat growth characteristics and annual wheat yields obtained using generated data were not significantly different from that obtained using actual data. Two simplified weather options were evaluated as input to the CERES-Wheat model. Mean daily solar radiation values by month produced the same wheat yield distributions as daily solar radiation data. Mean daily maximum and minimum temperature by month overestimated wheat yields compared to maximum and minimum temperature data that contained the day-to-day variations in temperature.
