I want to test the gravity wave option on a 4km WRF domain over mountaineous terrain using WRF4.1.5. The highest gwd input data in the standard wrf geog data is orogwd_10m, which is too coarse for my needs. Is there a program available which creates this data(oa1-oa4, ol1-ol4,conv), or do I need to write something by myself?

Kind regards
Hi Johannes,
Unfortunately we don't have any such program available. We are given the geog data from outside resources and don't create it ourselves. Hopefully someone else will see this post and be able to suggest something to make it easier for you!
