51 | ! ------------ |
---|
52 | !> Calculates large scale forcings (geostrophic wind and subsidence velocity) as well as surfaces |
---|
53 | !> fluxes dependent on time given in an external file (LSF_DATA). |
---|
54 | !> Moreover, module contains nudging routines, where u, v, pt and q are nudged to given profiles on |
---|
55 | !> a relaxation timescale tnudge. |
---|
56 | !> Profiles are read in from NUDGING_DATA. |
---|
57 | !> Code is based on Neggers et al. (2012) and also in parts on DALES and UCLA-LES. |
---|
58 | !> @todo: Revise reading of ASCII-files |
---|
59 | !> @todo: Remove unused variables and control flags |
---|
60 | !> @todo: Revise large-scale facing of surface variables |
---|
61 | !> @todo: Revise control flags lsf_exception, lsf_surf, lsf_vert, etc. |
