Dear colleagues,
I am setting up some CORDEX runs and have a question about sea ice in RegCM-4.4rc8.
Several of the CORDEX domains have coverage by sea ice. However there is no sea ice file for the ERA-Interim data.
Can someone give advice on how to include sea ice when using ERA-Interim for ic/bc? For physical consistency I would strongly prefer to use sea ice from ERA-Interim itself, but apparently this is not an option. (It is possible I will code it up if I have time.) However I am willing to consider other approaches.
Thanks for any suggestions you can give.
