Dear RegCM users,
we made serial of RegCM simulations over Siberian region, with my collegues. We found, that in some areas RegCM-landcover (with either BATS or CLM options) does not corresponds with real landcover. Especially, we were worried about lack of wetlands, because it should makes sensible impact on climate system. 

To solve this problem using BATS model, I had made changes in domain-file, changing landuse in area (near 150 000 km^2) on bog/marsh, but it made negligible effect on output parameters over this area, such as monthly precipitations.

In other simulation with CLM model I had changed percentage of wetland over this area (it was 0%) in corresponding .nc file, but influence on output parameters still was
too small and fragmentary.

I suspect that I do it wrong, and changes I made is not reasonobly. May be there is some other parameters, should be changed, to take an effect? Or, maybe, RegCM actually does not sensitive to such landuse changes? Please, help me understand.

Thanks for any help.
Best regards.
