- geocat.comp.meteorology.actual_saturation_vapor_pressure(tdew, tfill=nan)#
Compute ‘actual’ saturation vapor pressure [kPa] as described in the Food and Agriculture Organization (FAO) Irrigation and Drainage Paper 56 entitled:
Crop evapotranspiration - Guidelines for computing crop water requirement. Specifically, see equation 14 of Chapter 3.
The dew point temperature is synonymous with the wet bulb temperature.
Note that this function is the same as saturation_vapor_pressure, but with temperature = dew point temperature with different metadata
