Hi CMAQ users and developers,

I am trying to run CCTM, it shows these following error messages.

 |> Reading Emission Control Namelist:
 +======================================
 
 Performing Basic Error Checks for Emission Scaling Rules

GR_EM_SYM_DATE_0 | F
Error reading attribute VAR-LIST
netCDF error number -43 processing file “GR_EMIS_001”

 Could not open GR_EMIS_001                      file

Could any help me out?
I am also attaching the log files, Metadata of emission file, and running script with this post.

Hello Huan,

like the error message says, your emissions file does not have the required VAR-LIST attribute. Looking further at the ncdump of your emission file (emis_mole_all_2008001.txt), all emission variables are of type double rather than float, further violating conventions for CCTM emission files.

The underlying reason likely is the use of non-Fortran tools to generate this emission file since it results in a file not complying with I/O API conventions. Using Fortran tools than link in the I/O API library and then use those library functions to create and write to the emissions file would avoid these types of errors.
