Question about SMOKE output files

SMOKE
1

Hi,
I would appreciate if someone could help me understand about the SMOKE output files. In the output directory it creates two directories ‘cmaq.cb05ae6’ and ‘merge’. In the first directory it creates files starting with ‘pgts_l’ and in the second ‘inlnts’. I think CMAQ uses ‘inlnts’ file, then what is the use of other files? Also, I see that for my case ‘pgts_l’ files are 10 times larger than ‘inlnts’ files, is this normal?
Thanks
MMS

You can treat some point sources as an elevated sources based on their stack parameters. When the sources are chosen as elevated sources by Elevpoint program, CMAQ will treat them as inline sources to compute plume rise internally. The rest of point sources will be stay in the layer 1 and output them as “ptgts_l” gridded hourly surface emissions. Here is some information how those elevated sources are selected and handled within the SMOKE.

Thanks for the response. About sizes, you think that is normal?

Another quick question, where can i find the latest cross reference speciation files? The one have are missing with some SCC codes, such as the following SCC codes:
174063616
461373440
914358272
1946157056
2034237440
30700812
30701032
30701054
30701058
30701068
30701099
30701416
30701487
30700125
30700133
30700216

Thank you very much
