Chapter 11. Development of ET0 computation procedure.
Potential evapotranspiration (ET0) is a vital input to Water Balance calculations, which in turn are a vital part in Crop forecasting.
The parameters needed to calculate ET0 are the following:
Parameter group Parameters Remarks
- Temperatures : minimum and maximum in degrees celcius
- Radiation. Radiation can be calculated quite accurately from the number of sunshine hours (or sunshine fraction) accompanied by Day number in the year
