Running SMOKE using NEI2017

Hi everyone,

I am a new user of SMOKE. I installed SMOKE v4.8.1 last week and successfully ran the test case. The test case uses NEI2005 but I would like to use NEI2017. NEI2005 initially provided consists of several ASCII files. I found that the 2017 emissions modeling platform ( provides NEI2017( But the directory structure and file format of NEI2017 provided on the website are very different from those of NEI2005 initially provided. Do I have to run the scripts in if I want to run SMOKE using NEI2017? Could I download NEI2017 inventory data somewhere so I could run SMOKE through running these csh files provided for the test case as followed?

cd $SCRIPTS/run (change to the run scripts directory)
smk_area_nctox.csh (invoke the stationary area run script)
smk_bg_nctox.csh (invoke the BEIS3 biogenic run script)
smk_nonroad_nctox.csh (invoke the nonroad mobile run script)
smk_point_nctox.csh (invoke the point run script)
smk_rateperdistance_nctox.csh (invoke the MOVES mobile sources on-roadway rate-per-distance
(RPD) run script for all processes)
smk_ratepervehicle_nctox.csh (invoke the MOVES mobile sources off-network rate-per-vehicle
(RPV) run script)
smk_rateperprofile_nctox.csh (invoke the MOVES mobile sources off-network rate-per-profile
(RPP) run script)
smk_rateperhour_nctox.csh (invoke the MOVES mobile sources off-network rate-per-hour (RPH)
run script)
smk_mrgall_nctox.csh (invoke the all-sources merge script)
To verify that the nctox scripts have run correctly, go to the log file directory and look for errors by using:
cd $LOGS (change to the log file directory for the test case)

Thanks very much for your help!

We have updated the SMOKE test case to be 2017 NEI-based with SMOKE 4.9 because as you noted the nctox case is very old.

You could use 4.9 instead of 4.8.1 as there are some additional bug fixes in 4.9.

Yes, the structures are very different. You should download the 2017 platform package from

There is an informational text file:

and this file with the scripts and executables, although it sounds like you have working executables already:

There is a technical support document that describes the modeling sectors here:

Thank you very much for your reply! I am learning using the 2017 emissions modeling platform now.
