Shipping emissions version r4.36

[raonunes]

I'm trying to run EMEP version r4.36 using the shipping emissions inventory of the previous version r4.17. I know that shipping emissions are include in the GNFRemis_EMEP01_2015.nc file but I want to isolate them. I'm tried the new emission format but without success. I also tried red the file using the emis_inputlist(1)%name= 'DataDir/FMIGlobShip2015mon.nc', but also without success.

Any idea how I can use the emissions from the FMIGlobShip2015mon.nc file in the r4.36 version?

KR,

Rafael.

Hi Rafael,
I am not sure what is exactly in your FMIGlobShip2015mon.nc file. What did you try? Normally you can read NOx for example with (see documentation):

Emis_sourceFiles(1)%filename = 'DataDir/FMIGlobShip2015mon.nc',
Emis_sourceFiles(1)%periodicity='monthly',
Emis_sourceFiles(1)%source(1)%varname='NOx',
Emis_sourceFiles(1)%source(1)%species='nox',
Emis_sourceFiles(1)%source(1)%sector=8, ! assumes GNFR
Emis_sourceFiles(1)%source(1)%units='kg',

Hi Peter,
Thank you for your answer. I tried this form but not worked. My FMIGlobShip2015mon.nc is the shipping emissions file available in the r4.17 version (A global monthly shipping emissions file from FMI). I tried this form but not worked. However, I was able to use the new emission format to read emissions from the ECLIPSE V6b global emission fields GAIS model.

I can send you my config_emep.nml via email if you want to analyse.

Thank you!

I can send you my config_emep.nml via email if you want to analyse.

Yes, please, you can send me the config_emep.nml and the standard output (what you see "on the screen", that starts with Found 512 MPI processes available or similar)

The file FMIGlobShip2015mon.nc provided does not have a projection attribute. You can either add as global atttribute in the file:

projection = "lon lat" 

or add in the config_emep.nml:

Emis_sourceFiles(1)%projection='lon lat',

Then it should interpret the projection correctly.
I agree that the error message was not clear.

Hi Peter,
Thank you so much for your help!
Now with the projection information the shipping emissions were read.
The information below may be useful to someone...

Emis_sourceFiles(8)%filename = 'DataDir/FMIGlobShip2015mon.nc',
Emis_sourceFiles(8)%projection='lon lat',
Emis_sourceFiles(8)%periodicity='monthly',
Emis_sourceFiles(8)%source(8)%varname='NOx',
Emis_sourceFiles(8)%source(8)%species='nox',
Emis_sourceFiles(8)%source(8)%sector=8,
Emis_sourceFiles(8)%source(8)%units='kg',

One more question. As the file from FMI provide emissions of NOx, SOx, CO and particulate matter (divided in ash, EC, OC and SO4), in your opinion is correct read the particulate matter emissions as Emis_sourceFiles(8)%source(8)%species='pm25'?

[gitpeterwind]

Hi Rafael,
For details you should ask the people that made those emissions.
I do not see why you use the index 8 for sourceFiles and source; does that mean that you want to match pm25 with NOx emissions?
For our use, we have put the definitions as attribute in the file, so that they do not need to be specified in the config. That give the netcdf file as described below. You can put those values in the config instead if you prefer. The particles have been matched to individual species; you can also put them into pm25 if you do not look at the speciated pm anyway.
Maybe our ship emission expert @JanEiofJonson wants to add something.
