Dear WRF Supporters,
I'm using the static dataset modis_landuse_20class_15s_with_lakes. Unfortunately the Black Sea is considered as a lake, as you can see in the attached image. This causes WRF to use the Lake module if switched on.
My domain and simulations are focused on the Mediterranean area, and I will provide WRF with the SST for the Med, Black Sea and Atlantic Ocean from
a stand alone ocean model, and in future to be coupled with WRF into CIME. I realize that the SST provided over the Black Sea is not used by WRF, because it is considered as a lake. Am I correct?
In my case the optimal solution to solve definitely the issue would be to change the static field from 21 to 17 (only over the Black Sea), so that every time I would run geogrid in that area, the Black Sea will be ocean. Maybe other users not interested in air-sea coupling would complain because they could experience the inverse problem, using the lake model over the Black Sea.
Alternatively to the first hypothesis, assuming that the lake model runs on grid cells where LU_INDEX = 21, how can I change the LU_INDEX in the geo_em.d01.nc file, only over the Black Sea?
Which is your best recommendation?
Thank you very much.
Francesco
