earthkit.meteo.thermo.xarray.temperature_from_potential_temperature¶
- earthkit.meteo.thermo.xarray.temperature_from_potential_temperature(th, p)¶
Compute the temperature from potential temperature.
- Parameters:
th (
xarray.DataArray) – Potential temperature (K)p (
xarray.DataArray) – Pressure (Pa)
- Returns:
Temperature (K)
- Return type:
The computation is based on the following formula:
\[t = \theta (\frac{p}{10^{5}})^{\kappa}\]with \(\kappa = R_{d}/c_{pd}\) (see
earthkit.meteo.constants.kappa).
