Missing varaible SLTYP from MET_CRO_2D

I am using the MCIP v5.4 to generate data for CCTM but it raises an error Error interpolating variable SLTYP from MET_CRO_2D when I run with CCTM


I have checked the configuration/documentation and there is no information about setting up SLTYP in MCIP.
Any suggestions on how to fix it? Thanks!

I found the variable SLTYP exists in METCRO2D, so the error is CCTM can not interpolate this value.


Any suggestions on how to fix it? Thanks!
Or is there any method to explore the error, I tried to read log of CCTM but the information in not in detail

I found the solution here CMAQ5.3.1 CCTM run error “ Error interpolating variable SLTYP” - #3 by CN_CODER
