Emissions processors bedside


Besides, SMOKE are there any other emissions inventory processing package or software that can be used to prepare the emissions for CCTM?

Kindly let me know



Hi John,
No, there isn’t another emissions processing tool that is available to prepare emissions.
Do you have an issue with using SMOKE? What is the region that you would like to run the CCTM?

Hi Liz,

Please I have the following questions that I need some clarifications on. At the moment, I am creating a GRIDMASK file for CAMS emission inventory. We have followed the steps documented in https://docs.google.com/document/d/1veqEjaTPbDpkqHAIcyReokvv6MaENz0TrwOcFl1ewac/edit# .
my question is based on performing step 5. below

  1. Use zonal statistics in ArcMap to find the dominant country/ocean code and timezone offset in each inventory grid cell. You’ll need to do this in two steps, once for the country code and a second time for
    the timezone. Make sure to use the shapefile that has the X,Y attributes from step 4 as the zone data. Use “Majority” in ArcMap zonal stats to find the dominant coverage of the country code and time zone offset in each inventory grid.
    nice as zonal statistics is, it really struggles with large domains, and the EDGAR

0.1 degree domain is large. To circumvent system memory limitations in ArcMap we actually needed to divide the world into quarters, process each one separately, and then stitch
the resulting data together at the end.

  1. Join the outputs from zonal stats on the GRIDID for the country code and timezone so that you get both attributes in one file. 7. Export the joined results from the zonal statistics to a CSV file that contains the GRIDID, X, Y, country code, and timezone

At this stage of the process, all the files are vector shapes files and zonal statistics requires one or more of the world boarder time zone or gridded shape files to be a raster - which one of these should be a raster? and how have they done the zonal statistics
because it seems that some steps are missing from the documentation on how it was created.

Kindly let me know please

Best wishes
