I am trying to simulate WRF with 2km resultion over the grid e_we=1498; e_sn=761. Here Error in rsl.error.0000.

Kindly provide solution for same scheme of Physics...!
It looks like you're using the Pleim-Xu surface schemes, but you will need additional geographic static data to use that scheme. Take a look at this section on the static data downloads page:
You'll need to incorporate that data if you plan to use the Pleim-Xu schemes. Otherwise you can choose different schemes to use.
Thanks for your valuable suggestion.
Is there any option to use this scheme rather than U.S. region ?...
We don't have any data outside of the U.S., but there may be some out there that you can track down.

I have followed the given below schemes for my 3km domain with your earlier suggested Data (Geo static data for Pleim Xu). I just surprised, that WRF runs smoothly without any error. But my domain is different than US. Is this wrfout is valid output ?

sf_sfclay_physics = 1,
sf_surface_physics = 7,
sf_urban_physics = 0,
bl_pbl_physics = 5,
bldt = 0,
grav_settling = 0,
cu_physics = 3,
I apologize for the delay. I wanted to do a bit of research on this. I reached out to our physics specialist who said it looks like these particular data (from the static data web page) are only available for U.S. domains, but that if you are using MODIS (default) static data in other locations on the earth, it should be fine to use, along with this scheme - which is likely why you are able to have a successful simulation. So I would say you're okay to proceed as you are!
