specific_humidity_from_dewpoint#
- metpy.calc.specific_humidity_from_dewpoint(pressure, dewpoint, *, phase='liquid')[source]#
Calculate the specific humidity from the dewpoint temperature and pressure.
- Parameters:
pressure (
pint.Quantity
) – Pressuredewpoint (
pint.Quantity
) – Dewpoint temperaturephase ({'liquid', 'solid', 'auto'}) – Where applicable, adjust assumptions and constants to make calculation valid in
'liquid'
water (default) or'solid'
ice regimes.'auto'
will change regime based on determination of phase boundaries, eg temperature relative to freezing.
- Returns:
pint.Quantity
– Specific humidity
Examples
>>> from metpy.calc import specific_humidity_from_dewpoint >>> from metpy.units import units >>> specific_humidity_from_dewpoint(988 * units.hPa, 15 * units.degC).to('g/kg') <Quantity(10.791541, 'gram / kilogram')>
Changed in version 1.0: Changed signature from
(dewpoint, pressure)
