Detailed Description

Compute infrared flux divergence profile and downward flux at ground level relying on a 1D radiative scheme.

More precisely, compute atmospheric infrared (IR) radiation model quantities:

• vertical profile of IR flux divergence,
• downward IR flux at ground level
• upward and downward fluxes at different vertical levels
