Radiation
The radiation spectrum is divided into a long-wave part (thermal infrared) and a short-wave part (solar radiation). The radiation scheme (ecRad) performs computations of the short-wave and long-wave radiative fluxes using:
...
The radiation fluxes are then interpolated back to the original grid for use by surface radiation flux simulations (e.g. HTESSEL).
Fig2A.1.5.1-1: Radiation absorption and emission considered in the Radiation Scheme. Long-wave radiation calculations are complex. They include multiple absorption and emissions at the surface, by atmospheric moisture and cloud (possibly multilayered), and other constituents.
