Hello,

real.exe runs without errors.
My questions:
Best regards,
I am running WRF v4.6.0 with WRF-Lake enabled:
sf_lake_physics = 1, 1
Compared to a standard WRF run, I have:
- use MODIS land use (lakes identified correctly),
- provided static lake_depth,
- replaced lake SST/TSK in wrfinput_d0* using observed LST.
real.exe runs without errors.
My questions:
- Besides enabling sf_lake_physics and providing lake_depth, are there any other required or recommended steps specific to WRF-Lake?
- In namelist.wps, I used:
geog_data_res = 'default'
I noticed some users explicitly set:
geog_data_res = modis_landuse_20class_15s
Does using 'default' have any impact on lake mask, lake depth interpolation, or WRF-Lake behavior? - here‘s my namelist.wps
