dewpoint_from_specific_humidity

metpy.calc.dewpoint_from_specific_humidity(pressure, temperature, specific_humidity)

Calculate the dewpoint from specific humidity, temperature, and pressure.

Parameters:

• pressure (pint.Quantity) – Total atmospheric pressure

• temperature (pint.Quantity) – Air temperature

• specific_humidity (pint.Quantity) – Specific humidity of air

Returns:

pint.Quantity – Dew point temperature

Examples

>>> from metpy.calc import dewpoint_from_specific_humidity
>>> from metpy.units import units
>>> dewpoint_from_specific_humidity(1000 * units.hPa, 10 * units.degC, 5 * units('g/kg'))
<Quantity(3.73203192, 'degree_Celsius')>

Changed in version 1.0: Changed signature from (specific_humidity, temperature, pressure)
