The thermodynamics need to be better fitted to the observations. We want to use the

The SAFIRE-CORE dataset contains the absolute humidity in $g m^{-3}$. We can use this water vapour density directly to calculate the partial pressure of water vapour by using the ideal gas law. $e = R_V \rho_V T$.

Then we can calculate the saturation water vapour pressure $e_{sat}$ following three options:

Relative humidtiy is then defined as: $rh = \frac{e}{e_{sat}}$

The issue is that we get relative humidity values exceeding $100\%$ which very high supersaturation.
