CAMEO framework provides a unified database that integrates experimental observations, box model outputs, and detailed mechanistic information. Its querying functions and interactive visualization tools enable transparent and comprehensive comparisons between laboratory data and model predictions.
The Community Regional Atmospheric Chemistry Multiphase Mechanism (CRACMM) is a state-of-the-science chemical mechanism developed by the U.S. EPA for the Community Multiscale Air Quality Modeling System (CMAQ). This project aims to evaluate the accuracy of monoterpene chemistry representation in CRACMM using advanced mass spectrometry data, with a focus on detailed gas- and particle-phase products.
New chemical mechanisms for wildfire-derived VOCs were developed and evaluated using the SAPRC modeling system. This work also marked the first use of MechGen to connect gas-phase chemistry with SOA formation, advancing air quality modeling of wildfire emissions.
Chamber-derived secondary organic aerosol (SOA) yields from camphene are reported here for the first time. The influence of peroxy radicals (RO2) was investigated using chemically detailed box models. Notably, this study is the first to show that low concentrations of NO can enhance the formation of oxygenated organic molecules (HOMs) in the atmosphere.
