Dear All,I have the atmospheric output of coupled CESM1.1. However, they are in the sigma coordinate. Does anyone know how to switch the atmospheric output to the p coordinate?Many thanks

The software package NCL provides a function, 'vinth2p', that will interpolate CAM's levels to pressure levels of your choosing.
