pvdeg.humidity.water_saturation_pressure

pvdeg.humidity.water_saturation_pressure(temp, average=True)

Calculate the water saturation temperature or dew point for given vapor pressure.

Water saturation pressure (psat) model created from an emperical fit of ln(psat) vs temperature using a 6th order polynomial fit. The fit produced R²=0.999813. Calculation created by Michael Kempe, unpublished data. The fit used data from -40°C to 200°C.

Parameters:

tempseries, float

The air temperature (dry bulb) as a time-indexed series [°C]

averageboolean, default = True

If true, return both water saturation pressure serires and the average water saturation pressure (used for certain calcs)

Returns:

water_saturation_pressurearray, float

Saturation point

avg_water_saturation_pressurefloat, optional

Mean saturation point for the series given
