Gas-Phase Water-Soluble Organic Carbon: CMAQ Model Evaluation in Baltimore County
Prediction of gas-phase water-soluble organic carbon (WSOCg), a precursor for secondary organic aerosol formed through processing in atmospheric waters (aqSOA), has not yet been evaluated in models. We pair the WSOCg predictions from the U.S. EPA’s Community Multiscale Air Quality (CMAQ) model with continuous mist chamber measurements during February–March 2015 and August 2016 in Baltimore County, MD.
