| 41 | ! ------------ |
---|
| 42 | !> Calculates large scale forcings (geostrophic wind and subsidence velocity) as |
---|
| 43 | !> well as surfaces fluxes dependent on time given in an external file (LSF_DATA). |
---|
| 44 | !> Moreover, module contains nudging routines, where u, v, pt and q are nudged |
---|
| 45 | !> to given profiles on a relaxation timescale tnudge. |
---|
[2342] | 46 | !> Profiles are read in from NUDGING_DATA. |
---|
[2320] | 47 | !> Code is based on Neggers et al. (2012) and also in parts on DALES and UCLA-LES. |
---|
| 48 | !> @todo: Revise reading of ASCII-files |
---|
| 49 | !> @todo: Remove unused variables and control flags |
---|
| 50 | !> @todo: Revise large-scale facing of surface variables |
---|
| 51 | !> @todo: Revise control flags lsf_exception, lsf_surf, lsf_vert, etc. |
