CMAQ emissions for AirScreen

CMAQ
1

Hi all, I would like to ask where I can find the emission files that are being used by the 2020 AirToxScreen assessment ( 2020 AirToxScreen: Assessment Results | US EPA ). The website says that the emission starts from NEI, while I think there are lots of updates (the inclusion of air toxics) in the inventory.

Any comments are highly appreciated!

Hi Alison,

Thanks for the message. I did find this when I was trying to search for the data. May I ask whether the pre-merged netCDF emission files are available for the 2020 AirToxScreen assessment?

Thanks!

Best regards,

Ryan

The pre-merged emissions files are available through the UNC Dataverse (2020 Modeling Emissions).

The premerged emissions are linked from the last link of the 2020 platform page which points to the UNC dataverse:

On that page, see “File Location and Download Instructions:” an

Hi Alison, may I ask where I can find the SMOKE outputs for the 2018v1 Platform (for AirToxScreen)? I only find the 2018v2 in the CMAS data warehouse.

Best regards,
