Figures for EPA White Paper EPA-454/R-21-008: Overview of Progress and Findings from the Cross-EPA Coordination Effort for Understanding and Evaluating NOx Emissions Discrepancies

Metadata Updated: January 24, 2022

This white paper describes the EPA exploration of a reported discrepancy between estimates of NOX and reactive nitrogen (NOY) concentrations from the Community Multiscale Air Quality (CMAQ) model and ambient measurements. The paper summarizes analysis that has been published in Toro et al. (2021) and Appel et al. (2017). The data used in those publications is publicly available from Zenodo and data.gov (links below).
