Hi,

I need to run the NEI 2019 platform with Hg. I noticed that the scripts and inputs packaged for the 2019 platform are for standard CAP-focused modeling and does not include Hg. What scripts and inputs should i use if i want to include Hg emissions.

Thanks,  
Lin

You’ll need to look at the 2020 scripts and how they use the files I pointed you to and to compare to 2019.

For example, the INVTABLE and speciation profiles.

We don’t have the 2019 scripts with Hg available right now.
