1. Modifications to avoid NEC Compiler Problems in TERRA

Because of problems with the NEC compiler for the module sfc_terra, we updated this module with the latest ICON Version. Modifications are:

• A bug fix:
  Use snow-weighted potential evaporation to ensure that sum of evaporation terms does not exceed potential evaporation (Sect. I.4.4). Up to now the usual potential evaporation was used, which could lead to too low evaporation, if the soil under the snow is colder than the snow surface. This bug fix modifies the results slightly, at grid points where there is snow.
• Removal of all index lists. It turns out that vectorization of usual DO loops on the NEC is sufficient fast.

2. Modifications to EMVORADO

• Modified organization of Mie look up tables.
• Add missing entries for some new namelist parameters in glob_nml% type.
• Organization of restart runs.

5. Changes of Results

The bug fix in sfc_terra.f90 modifies the results at grid points, where snow is lying.
