Hi - I am trying to process onroad emissions (these, from the 2017 platform: ftp://newftp.epa.gov/air/emismod/2017/2017emissions/2017gb_onroad_SMOKE-MOVES_emissions_FF10_29jun2020.zip ) as nonpoint.
I found these scripts to try to accomplish this: https://gaftp.epa.gov/Air/emismod/2017/onroad_as_nonpoint_saprc_speciation_scripts_inputs.zip
But I am using CB6 mechanism (specifically CMAQ_CB6+AERO6), not SAPRC. Are there GSPRO and GSREF files on the ftp somewhere that I can use? I note that the readme for the onroad as nonpoint suggests using the Speciation Tool to create a new GSPRO file for a new chemical mechanism. But I do not have the Speciation tool nor do I know how to use it
