Hi CMAQ users:

I am trying to run CCTM on the latest 5.3 version, using the same input I prepared and successfully run on version 5.2.1. However, it shows these following error messages:

> * * *
> 
> \*\* Runscript Detected an Error: CGRID file was not written. \*\*  
> \*\* This indicates that CMAQ was interrupted or an issue \*\*  
> \*\* exists with writing output. The runscript will now \*\*  
> \*\* abort rather than proceeding to subsequent days. \*\*
> 
> * * *

What shall I do?

Best  
Huan

Hi Huan,  
This error indicates your run did not complete successfully.  
Please look in the

```auto
output_*/LOGS directory

```

for the per processor logs such as  
CTM\_LOG\_000.v53\*  
Use grep or an editor such as vi to search for an error message within those log files that may indicate why the run did not complete successfully.

Thanks for your response. It is about processing the raw emission inventory files into CMAQ-ready files. For instance, MEIC and REAS2 anthropogenic files.

Thanks in anticipation

You need to make sure your emission files, meteorology files, BCON and ICON files have the same coordinate
