Kelsey,
If only the minimum weather data set is available, then the model will use
the Priestley-Taylor method. To use Penman-Monteith-FAO56 method you will
need information on wind and dew-point temperature.
Best regards,
Jon

Asunto: Evapotranspiration Model
Hi all,
If we only have a minimum data set (SRAD, Minimum Temperature, Maximum
Temperature and Precipitation), and select FAO56 as our evapotranspiration
model, what model is actually used? Does DSSAT default to a certain model,
or will it calculate values so it can use the FAO56 model?
Thanks,
Kelsey
