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