Hello!
I am currently trying to run the MPAS-CMAQ model, and recently, I attempted to create the soil nudging file mentioned in the test file. I understand that this file supports the PX LSM. In WRF, the OBSGRID is typically used to generate this file, but I couldn’t find a similar feature in the MPAS documentation. Also, when I used the ncdump -h command to examine the x1.40962.soilndg.2017.nc file from the test file, I found that it is generated by MPAS’s init_atmosphere, and this version of MPAS appears to be modified by USEPA but not publicly available. So, how can I generate this file? Should I use WRF’s OBSGRID to create the file and then interpolate it to MPAS, or can I use the standard init_atmosphere to generate it?
I am looking forward to your response.
Sincerely,
Pan.
