Dataset supporting "Comparison of ozone formation attribution techniques in the northeastern United States"
The Integrated Source Apportionment Method (ISAM) has been revised in the Community Multiscale Air Quality (CMAQ) model. This work updates ISAM to maximize its flexibility, particularly for ozone (O3) modeling, by providing multiple attribution options, including products inheriting attribution fully from nitrogen oxide reactants, fully from volatile organic compound (VOC) reactants, equally
from all reactants, or dynamically from NOx or VOC reactants based on the indicator gross production ratio of hydrogen
peroxide (H2O2) to nitric acid (HNO3). The updated ISAM has been incorporated into the most recent publicly accessible
versions of CMAQ (v5.3.2 and beyond). This study’s primary objective is to document these ISAM updates and
demonstrate their impacts on source apportionment results for O3 and its precursors. Additionally, the ISAM results are
compared with the Ozone Source Apportionment Technology (OSAT) in the Comprehensive Air-quality Model with
Extensions (CAMx) and the brute-force method (BF).
