The following physical expressions are currently available for model 303 in the new_diag framework and in the jorek2_postproc diagnostics. Available expressions may differ between models. The easiest for getting an up to date list is to compile jorek2_postproc, execute it interactively and call the command expressions which produces a complete list.
