saturation_vapor_pressure¶

metpy.calc.saturation_vapor_pressure(temperature)[source]¶

Calculate the saturation water vapor (partial) pressure.

Parameters: temperature (pint.Quantity) – air temperature
Returns: pint.Quantity – The 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:

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