Potential temperature

Computes potential temperature Poisson’s Equation [Wallace2006] (Eqn. 3.54 on pg. 78),

\[\Theta = T (P_0 / P)^\kappa\]

where \(P_0\) is the reference pressure in hPa and \(\kappa\) is the dimensionless quantity \(R/C_p\).

Parameters:

• temperature (DataArray) – Temperature in Kelvin

• pressure (DataArray) – Pressure in hPa

Return type:

DataArray
