Impact of open crop residual burning on air quality over Central Eastern China during the Mount Tai Experiment 2006 (MTX2006)

Open crop residual burning (OCRB) significantly impacts air quality over Central Eastern China, particularly during the Mount Tai Experiment 2006 (MTX2006). The study found that OCRB contributed substantially to concentrations of ozone (O3), carbon monoxide (CO), black carbon (BC), and organic carbon (OC) at the summit of Mount Taishan. Using a regional chemical transport model, researchers demonstrated that daily OCRB emissions were crucial for accurately capturing pollutant variations, with OCRB accounting for 26% of O3, 62% of CO, 79% of BC, and 80% of OC during high-pollution episodes. The findings highlight the importance of considering OCRB in air quality assessments, as it affects both primary and secondary pollutants, including ozone, over northeastern Asia.
