Model Code Changes
| Section | |||||
|---|---|---|---|---|---|
The source code changes to run OpenIFS 43r3 in nudged configuration are under version control in the OpenIFS Git repository in branch feature/nudging.
In order to control the model's nudging configuration the following source code files are relevant:
The code in the nudging branch of OpenIFS 43r3 differs from that in IFS insofar that the variables CLPSHRLX and CLPGGRLX have been added to the namelist. These two variables allow to specify the location of the directory with the forcing files on the file system. If these are not set then the model will expect to find the forcing files in the experiment directory. The relaxation to the analyses involves code in further routines (e.g. |
