Dataset contains CMAQv5.3-predicted hourly average concentrations of organic aerosol and other species (HO2, NO, NO3, O3, OH) for Hyytiala, Finland (___location of BAECC field campaign) and Centreville, AL, USA (main ___location of SOAS field campaign) for 2016. How species were created from raw CMAQ output is defined in Table S2 of the paper this data supports. CMAQ v5.3 code is also linked here. The specific configuration of CMAQ is described in the manuscript associated with this data.
