Thanks for your reply, I am using NEI 2011 and SMOKE-3.6. Yes i am trying to include Hg emissions. I am using the following INVTABLE: invtable_2011v2_platform_cb6_integrate_12mar2015_v1.txt
And i changed the following two lines, changed KEEP to Y:
HGSUM EXH EXH__7439976 Y 1.0 Y N tons/yr Mercury, unspeciated
HGSUM 7439976 Y 1.0 Y N tons/yr Mercury, Unspeciated Mercury
One quick thing that may or may not help: set NO_SPC_ZERO_EMIS to Y, if it is not already set that way.
If it’s already set to Y, or if changing that parameter doesn’t solve the error, that means your GSREF doesn’t contain mercury speciation profile assignments for all of the SCCs with mercury emissions in their inventory. We suggest using the GSREF and GSPRO from the 2020 platform (https://gaftp.epa.gov/Air/emismod/2020/ancillary_data/), in case more SCCs are covered there. If you run into the same error after that, you’ll need to add speciation profile assignments to the GSREF for all of the SCCs that have HGSUM emissions but don’t have an HGSUM profile assignment.
If you run into further problems, please provide the Smkinven and Spcmat logs
