saturation_vapor_pressure

metpy.calc.saturation_vapor_pressure(temperature)

Calculate the saturation water vapor (partial) pressure.

Parameters

temperature (pint.Quantity) – Air temperature

Returns

pint.Quantity – Saturation water vapor (partial) pressure

See also

vapor_pressure, dewpoint

Notes

Instead of temperature, dewpoint may be used in order to calculate the actual (ambient) water vapor (partial) pressure.

The formula used is that from [Bolton1980] for T in degrees Celsius:

\[6.112 e^\frac{17.67T}{T + 243.5}\]
