Hi,  
I found that EQUATES published CMAQ daily average surface concentrations for 14 species for 2002-2019. I’d like to ask if EPA has CMAQ output for the US in 2021.  
And does EPA have a plan to publish SMOKE-processed NEI for 2021, especially ptegu emissions, like they did for previous years. If so, when do they plan to publish the data?

Thanks,  
Huazhen

Hi Huazhen,

I believe that this dataverse entry will provide information about the emissions data for 2021.
