The grass reference evapotranspiration is 0.00 mm/hour between 02.00 and 03.00 hours and 0.63 mm/hour between 14.00 and 15.00 hours. Calculation procedures with missing data The meteorological data, required to estimate ET o by means of the FAO Penman-Monteith equation, consist of air temperature, air humidity, wind speed and radiation.

Penman-Monteith equation (4) for a hypothetical crop is given as, where ET sz = the standardized reference evapotranspiration for grass (ET os) or alfalfa (ET rs) in units based on the time step of mm d-1 for a 24-h day or mm h for an hourly time step, C n = the numerator constant for the reference crop type and time step and C

The Penman Monteith method implements the Penman Monteith equations for computing evapotranspiration at less than a daily time interval as detailed by Allen, Pereira, Raes, and Smith (1998). The equations are based on a combination of an energy balance with a mass transfer.

From the original Penman-Monteith equation (Equation 3) and the equations of the aerodynamic (Equation 4) and surface resistance (Equation 5), the FAO Penman-Monteith method to estimate ET o can be derived (Box 6): (6) where ET o reference evapotranspiration [mm day-1], R n net radiation at the crop surface [MJ m-2 day-1],
