We recommend that instead of running SMOKE-MOVES, you use the provided county-total onroad emissions here:

[https://gaftp.epa.gov/Air/emismod/2016/v1/2016emissions/2016fh\_onroad\_SMOKE-MOVES\_emissions\_FF10\_27sep2019.zip](https://gaftp.epa.gov/Air/emismod/2016/v1/2016emissions/2016fh_onroad_SMOKE-MOVES_emissions_FF10_27sep2019.zip)

using the package here:

[https://gaftp.epa.gov/Air/emismod/2017/onroad\_as\_nonpoint\_saprc\_speciation\_scripts\_inputs.zip](https://gaftp.epa.gov/Air/emismod/2017/onroad_as_nonpoint_saprc_speciation_scripts_inputs.zip)

You can use the package posted under 2017 with the 2016 emissions. Just replace the inventories (there are two, EMISINV\_A and EMISINV\_B) in the run script with the 2016fh onroad FF10 (that would just be EMISINV\_A).

For othpt, does your domain require parts of Canada?
