View charts of geographic contributions to Daily Maximum 8-Hour Ozone Concentrations at AQS and CASTNet monitoring sites in the 4km and 12km WAQS modeling domains, and across a virtual receptor grid within the 12km modeling domain.
Source Apportionment - WAQS 2011b Round 2
WAQS 2011b Round 2
View charts of source category-specific contributions to Daily Maximum 8-Hour Ozone Concentrations at AQS and CASTNet monitoring sites in the WAQS 4km and 12km modeling domains, and across a virtual receptor grid within the 12km modeling domain.
Source Apportionment - SNMOS
Southern New Mexico Ozone Study (SNMOS)
The Southern New Mexico Ozone Study (SNMOS) is conducting photochemical grid model (PGM) modeling to help understand the causes of observed high ozone concentrations in Doña Ana County in southern New Mexico. Source apportionment modeling is based on the WAQS 2011b CAMx AQ modeling results for 2011 base year and 2025 future case modeling scenarios.
Source Apportionment - Denver Metro/Northern Front Range
Denver Metro/Northern Front Range - Local Source Analysis
2017 Ozone Source Apportionment Modeling for the 2008 0.075 ppm ozone NAAQS. The Local Source Analysis analyzed ozone contributions from different source sectors within Colorado. Source apportionment modeling is based on the WAQS 2011b CAMx AQ modeling results.
