To help us troubleshoot this problem, could you please recompile the executable in debug mode, rerun the script, and post both your run script and log file?

In addition, it seems you are running CMAQv5.3.2. If the VGTYP for your coarse and fine grids is -9999 (hybrid coordinate), please use CMAQv5.3.3 and see this recent thread for further details.

follow is my run script
if ( $BCON_TYPE == regrid ) then

setenv CTM_CONC_1 /work/MOD3EVAL/sjr/CCTM_CONC_v53_intel18.0_2016_CONUS_test_${YYYYMMDD}.nc

Similar to the discussion in the other thread I referenced, it seems your CTM_CONC_1 file has a single layer only which will not work to create 3D initial and boundary conditions for your target domain. Please make sure that the vertical extent of your coarse grid input file covers the vertical extent of your target domain.

how do I set up CCTM files to solve this problem, and where do I to set up vertical extent, thank you very much.

7

Environment variables controlling CCTM options are documented in Appendix A of the User’s Guide. See variable CONC_BLEV_ELEV under CCTM Configuration options for changing the vertical extent of your CCTM_CONC output files.

I’ll try it on right away.you solved a big problem for me.
