Hi all,
I am using NEI 2011 v6.2 platform to prepare emission data. I am able to run all those sectors successfully but Hg is not included in the final emission files. I wonder what should i change to include HG. Also, is HG included in NEI 2011 HGSUM or speciated HG (HGIIGAS, PHGI and HG) ?
Thanks,
Lin

Hi all,
Just an update of the question, I changed the two lines of the INVTABLE to the following:
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
and used gsref\_toxic, gspro\_toxic files. There are HG,HGIIGAS and PHGI variables in the output emission files but the emission values are 0. Still working on it.

Can you please provide your INVTABLE, GSREF, and GSPRO, and their Smkinven and Spcmat logs?
