The following documents describe annual adjusted Community Multi-scale Air Quality (CMAQ) deposition fields for the years 2002-2012 and for 2025, with a bi-directional NH3 formulation and a dynamic confined animal feeding operations (CAFO) emissions profile for critical loads analyses and as input to other ecological models where the most accurate wet deposition fields are desired (via precipitation and bias adjustments).
Each document describes the metadata needed to analyze and interpret the CMAQ runs.You may need Adobe Reader to view files on this page. See EPA’s About PDF page to learn more.
