ERROR ABORT in subroutine VDIFFACMX on PE 055

CMAQ Run Time Errors and Issues

Hi,
I was running a year-long simulation from 1st January to 31st December. But my run is aborting on 2nd March. It is not creating the C_SGRID file for 2nd March. My log script is showing the following error:

—>> WARNING in subroutine GET_EMIS on PE 055
Could not read HGIIGAS from EMIS_1

I am not understanding what the error message is pointing or what should be my next step.
I followed the thread regarding ’ why C_SGRID is not creating and check with the run script settings like MAXSYNC etc. I also found that previously one person got the same error, but could not reach any decision from that thread. I would be grateful if anyone can help me with this issue.

As a first check, let’s see whether the data is in fact missing for file EMIS_1 and date&time 2016062:224900 – a quick and easy way to do that is to run M3Tools program m3stat:
% setenv EMIS_1 <path>
% m3stat EMIS_1 DEFAULT >& EMIS1.stats
and then look at EMIS1.stats with your favorite text editor to see whether it also says that date&time is not available. If it isn’t, it probably means something went wrong (or missing) with your emissions processing…

Thanks for your suggestion. I tried to run the M3Tools and getting the error “m3stat: Command not found”.
May be I am not running it properly. Actually, I just follow the above mentioned steps in my CMAQ_HOME directory. Do I have to compile/bluid anything before running the m3stat commnad?

If you built the I/O API, you will have also built the M3Tools programs; after the build. they will be found in the same directiory as libioapi.a. You might do well to add this directory to your PATH. See https://www.cmascenter.org/ioapi/documentation/all_versions/html/AA.html#tools

Among these programs is m3stat, which is documented at https://www.cmascenter.org/ioapi/documentation/all_versions/html/M3STAT.html

Hello,

I appreciate your help. That was helpful. I did check the Emis_1 file and it looks like no data is missing for (2016062:224900). Do you have any other suggestions for me?

Thanks,
Sadia

I think something may be wrong with the scripting here: that

Date and time 3:28:04 (*******:032764)

suggests that something has gone wrong with the date-handling…

Thanks for your suggestion. As I am very novice in this field, could you please also suggest some potential files to check which I might have the problem. Sorry for bothering you repeatedly.

Sadia
