Strange output at boundaries

Hi,
I am using ndown to generate boundary conditions for an inner domain. The wrf output of this inner domain however contains narrow bands of strange values at the boundaries. I have given the output of rain variables, but holds true for T2 variable as well. The distinctiveness of the bands increases with the model output time. I am using WRF-4.1.3.
Kindly help in resolving this issue.

Hi,
Can you send the namelists you use to run d01, to run ndown, and then I assume this one you sent is for d02? Is that correct? Thanks.

Yes,they were for d02.
I have attached for d01.

Thanks.

Hi,
I'm not sure if this would have anything to do with it, but try setting nproc_x/y to the same thing you set for the original simulation. Those differ between your namelists. Are you running WRF-Chem? If so, does this happen if you run this on a non-chem build of WRF (just basic WRF)? Thanks!
