I'm a beginner with WRF, but am looking to run a simulation with a real atmosphere, but idealized surface conditions. Specifically, I want to change the soil temperature and moisture fields to represent a domain of continuous permafrost. I was told that I would need to modify the metgrid output to procure this idealized state, but was not given any direction on how to do so. After a few hours of Googling, I decided to come to the forum to ask where I should be modifying scripts to create the surface and soil conditions that I'm hoping for.
Is it as simple as doing something within METGRID.TBL or does code need to be written in one of the main modules within metgrid? I'd appreciate any help provided (or even a link to a page where an answer already exists that I might have missed). Thanks in advance!
