NetCDF issue with CMAQ run

CMAQ Run Time Errors and Issues
1

Hello,all;

I ran into this following issue on NetCDF dimension.

Checking header data for file: A_CONC_1
NCVGT: : NetCDF: Start+count exceeds dimension bound
NCVGT: : NetCDF: Index exceeds dimension bound
NCVGT: : NetCDF: Index exceeds dimension bound
NCVGT: : NetCDF: Index exceeds dimension bound

I asked our HPC or cluster support and they wanted me to check my settings. Could you point me to the settings that I can change? Below is my current settings if it is related with the issue.

#> Output Species and Layer Options
#> CONC file species; comment or set to “ALL” to write all species to CONC
setenv CONC_SPCS “ALL”
setenv CONC_BLEV_ELEV " 1 1" #> CONC file layer range; comment to write all layers to CONC

#> ACONC file species; comment or set to “ALL” to write all species to ACONC
setenv AVG_CONC_SPCS “ALL”
setenv ACONC_BLEV_ELEV " 1 1" #> ACONC file layer range; comment to write all layers to ACONC
setenv ACONC_END_TIME N #> override default beginning ACON timestamp [ default: N ]

Appreciate!

Hi Yijia:
You may need to ensure the dimension of your emission file, mcip output, icon output are the same

To check those dimensions generally, use “ncdump -h”. Also look at the starting date&time attributes and compare them with the date&time attributes for your model run (errors in that could cause the “Start+count exceeds dimension bound”).
