Air Quality Modeling

Overview
IWDW Air Quality Modeling Platforms include WAQS AQ modeling platforms, derivative platforms that are based on WAQS platforms, AQ modeling platform provided by the EPA, and legacy 3SAQS platforms (The 3SAQS was the predecessor to the WAQS). To view modeling platform file contents, or to request data files from a modeling platform, click on either a WAQS or External Modeling Platform link, below. The IWDW also hosts a WAQS 2014 modeling platform wiki.

WAQS Modeling Platforms Select a modeling platform to request data and view file details
WAQS Air Quality Modeling Platforms are developed with oversight by WAQS Cooperators. The platforms include modeling software, NEI based emissions with updates for the intermountain west region, meteorology, boundary conditions and other AQ model inputs, and 3D model outputs. Recent WAQS platforms include inputs and software to run CAMx and CMAQ. Scripts and ancillary data for SMOKE emissions processing are included in the platform distributions. Click on the links below to browse respective WAQS and 3SAQS (the 3SAQS, or Three State Air Qulaity Study, was the predecessor to the WAQS) modeling platform contents.
External Modeling Platforms Select a modeling platform to request data and view file details
External platforms are modeling platforms either wholly or partially developed by groups external to the WAQS. Derivative platforms are those that are developed by organizations external to the WAQS, although they made use of some components of a WAQS platforms. The IWDW also provides access to modeling platforms developed by the USEPA.
The links below lead to visualization tools for source apportionment modeling results. The tools and SA modeling were produced by Ramboll-Environ. Some of the SA modeling studies have wiki pages with detailed information on the modeling approach and additional documentation (see wiki links, below). An additional SA wiki provides information on the use of particulate source apportionment modeling to identify most impaired visibility days in IMPROVE monitoring data.
To do:
  1. Add 2011_v2 to 2011b platform description
  2. Follow up with MH on MT study for external platforms
  3. Develop platform descriptions for CARRMS, SNMOS, DNFR
