NEI2016 MET and premerged data on IWDW

SMOKE Emissions Inventory
1

Hi all,

I am trying to download, 12km premerged data, ICBC, and MET data from IWDW, and noticed the domains for different data are slightly different, example
2016 Premerged gridded emissions only 12US1 available,
CMAQ-ready MCIP data (12K) and CMAQ-ready ICs and BCs (12k), 12US2 available
2016 Premerged point emissions, 12US1 and 12US2 available,

Just wonder is 12US1 also available for CMAQ-ready MCIP data (12K) and CMAQ-ready ICs and BCs (12k)?

If not, it is OK, we can use m3wndw to trim down 12US1 2016 Premerged gridded emissions.

Thanks
Joey

Hi Joey, 12US1 emission files were prepared because it allows us to see the emissions farther into Canada and Mexico, but we don’t plan to post the 12US1 meteorological data in addition to what is there. The premerged point source emissions can be used as-is to model 12US2. You are correct to use m3wndw to trim down the gridded emissions.
