With the implementation of the COSMO-ICON Physics several new namelist variables have been introduced. Also, some namelist variables from the old scheme have been removed. Of course, new namelist variables or changes to existing variables also resulted from other developments. In the following we want to give an overview on the most important changes.
All tables contain a column with the COSMO Version, in which the corresponding namelist variable has been introduced / modified / deleted. Please take a look to the Release Notes of these versions to get more information.
First we summarize all variables that have been deleted and are no more available in Version 5.05. Please remove all these variables from your Namelist input.
| Group | Name | Deleted in Version | Short Explanation |
|---|---|---|---|
| /PHYCTL/ | lmulti_layer | 5.04f | Old 2-layer soil model has been removed. |
| nlgw | 5.04f | ||
| /TUNING/ | wichfakt | 5.04f | Not used in new formulation of turbulence scheme. |
| securi | 5.04f | ||
| /GRIBIN/ | nlgw_ini | 5.04f | Old 2-layer soil model has been removed. |
| nlgw_bd | 5.04f |
For the following variables there have been modifications to the defaults and / or to the allowable range of values.

Note that there have also been several new namelist variables in /PHYCTL/ and in /TUNING/ for the IFS Bechtold convection scheme, which is implemented in COSMO as an option. Please take a look to the Release Notes of versions 5.04b and 5.04h, resp.
