MEGAN TXT2IOAPI Execution Error: “ERROR ABORT in subroutine CNVT_EFS”

MEGAN
1

Hi all,
I have tried to run the MEGAN3.2 model (compiled by gfortran) and I finished the first two steps (Pre-processing and Emission Factor Processing) successfully. I started the last step (Emission Rate Estimator) by executing the TXT2IOAPI program (run.txt2ioapi.v32.csh) but I got “ERROR ABORT in subroutine CNVT_EFS”. I was unable to identify the issue’s root cause.
The logfile is:

Thank you for any help in advance.

Shouldn’t your GRIDDESC have:

’ ’
‘LambertConformal’
2 30.000 60.000 24.000 24.000 45.000
’ ’
‘marmara_4km’
‘LambertConformal’ 159999.312 -610361.625 4000.000 4000.000 94 79 1
’ ’

since

 Value for GDNAM3D:  'marmara_4km'

@willison.jeff
Thank you for your response. In the GRIDDESC file, the domain name is defined as '4km’. Is this mean that I should change the GDNAM3D value to ‘4km’, in the MEGAN?

You can change it in the GRIDDESC or in the .csh file. They just have to agree with each other.
