The Exner function is an important parameter in atmospheric modeling. The Exner function can be viewed as non-dimensionalized pressure and can be defined as:

$\mathrm{\Pi }={\left(\frac{p}{p_0}\right)}^{R_d/c_p}=\frac{T}{\theta }$

where $p_0$ is the pressure at the surface, usually taken as 1000 hPa; $R_d$ is the gas constant for dry air; $c_p$ is the heat capacity of dry air at constant pressure; $T$ is the absolute temperature; and $\theta$ is the potential temperature.
