Note that initial release of the 2016beta platform does not include the 2023 and 2028 future inventories. These data will be released as an update to the platform.

Description

In late 2017, a group of state, local, tribal, regional, and federal air planning agencies initiated a collaborative process to build a national emissions modeling platform (EMP) for simulating air quality in the U.S. The 2016beta EMP is the first product from the National Emissions Inventory Collaborative that includes a full suite of base year (2016) and future year (2023 & 2028) inventories, ancillary emissions data, and scripts and software for preparing the emissions for air quality modeling.

A coordination workgroup, ten sector workgroups, and a modeling workgroup were staffed by over 245 state and regional air agency, EPA, and Federal Land Manager employees. The work of the sector workgroups to build 2016 base year and future year inventories is documented in a series of sector-specific specification sheets below. These specification sheets detail the origin of the inventories and ancillary data used to simulate criteria pollutant, and in many cases hazardous air pollutant, emissions for the U.S., Canada, and Mexico.

The summary stacked bar plots below compare U.S. total criteria pollutant emissions for the 2016beta platform back to 2011 and 2014 base and future year emissions.

Documentation

The documentation is available as a separate document for each modeling sector:

  • Oil & Gas - Nonpoint
  • Oil & Gas - Point

  • Point - EGU - ERTAC
  • Point - EGU - IPM
  • Point - non-IPM
  • Point - Fires - Agricultural
  • Point - Fires - Wild and Prescribed

  • Canada - Mobile - Onroad
  • Mexico - Mobile - Onroad
  • Canada/Mexico - Point
  • Canada/Mexico - Point - Fires
  • Canada/Mexico - Nonpoint

Summary Plots

Descriptions of the emissions platform cases shown in the plots below are as follows:

  • 2011en, 2023en, 2028el = Final 2011, 2023, and 2028 cases from the 2011v6.3 platform
  • 2014fd = NEI2014v2 and 2014 NATA
  • 2016ff , 2023ff, 2028ff = 2016beta platform

Acknowledgements

Assembling, evaluating, and documenting the initial release of the 2016beta platform involved over 245 committed air quality scientists across multiple state, local, tribal, and regional agencies, and EPA and Federal Land Management agencies. Several consultants and industry employees contributed to the workgroups through participating in conference calls and presenting on important inventory developments that were relevant to the Collaborative.

Particular acknowledgement of the workgroup co-leads is due, as they worked to recruit, organize, and lead their workgroups through the Collaborative platform development and documentation process.

Refer to the Collaborative inventory workgroup wikis for complete lists of the workgroup co-leads and participants.
