saturation_vapor_pressure

metpy.calc.saturation_vapor_pressure(temperature)[source]

Calculate the saturation water vapor (partial) pressure.

Parameters:temperature (pint.Quantity) – The temperature
Returns:pint.Quantity – The saturation water vapor (partial) pressure

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:

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