Hi all,
We used EQUATES data to conduct CMAQ simulations to 2019. Does EPA have any similar emissions after 2019, say 2020, 2021, 2022? We want to continue our modeling project to more recent years. Thanks!

There are currently no post-2019 emissions consistent with the EQUATES methods. EPA has provided emissions modeling platforms for 2020, 2021, and 2022 based on the 2020 National Emissions Inventory (2020-2022 Air Emissions Modeling Platforms | US EPA). Each platform has a technical support document that can be used to help identify differences in model versions, input data, and ancillary data.

Thanks for your guidance. One more question, did EPA create BCs, MCIP, and other auxiliary files associated with the inventory? We are running CMAQ at 12US1 domain.
Yes, all are available as part of the AWS open data program. The 2020 (https://doi.org/10.15139/S3/W4HCMV) and 2021 (2021 North American Emissions Modeling Platform - CMAS Data Warehouse) packages are referenced on the CMAS Data Warehouse (https://dataverse.unc.edu/dataverse/cmascenter). Information on the 2022 platform can found in this record: OAQPS 2022 Modeling Platform - Registry of Open Data on AWS
As noted, these modeling platforms are developed for the purposes described in each technical support document. There are differences in these platforms that will result in discontinuities with EQUATES.

HI James,
Thanks a lot for your information. I have checked the AWS and downloaded several day for a test run. Do you know where I can get the details information about the CMAQ version and run script? We want to follow the EPA guidance to conduct these simulations.

The run scripts are available with the platform data, ex.:
