In this work, the concentrations of these two aldehydes were simultaneously measured online at a regional site in Jiangsu Province (China) during the 2018 EXPLORE-YRD campaign. The maximum measured concentration of GLY and MGLY was 0.47 and 6.68 ppb, respectively. As the campaign site was surrounded by farmland and the observations were recorded during harvest, significant enhancements to the concentration of GLY and MGLY were found owing to agricultural biomass burning. While the enhancement of MGLY relative to CO (0.0059 +/- 0.0012) was found to be consistent with previous study, the corresponding enhancement ratios of GLY were lower (0.0003 +/- 0.0001). The possibility of using the ratios between formaldehyde (HCHO), GLY, and MGLY concentrations as indicators of reactive VOC composition was investigated. Based on measured data and model simulation results, we found that the MGLY to HCHO ratio was sensitive to VOC precursors and reasonably well correlated with the reactivity of aromatics.</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:000558539100008</style></accession-num><notes><style face="normal" font="default" size="100%">&lt;p&gt;My6qkTimes Cited:1Cited References Count:55&lt;/p&gt;</style></notes><auth-address><style face="normal" font="default" size="100%">Peking Univ, Coll Environm Sci &amp;amp;amp; Engn, State Key Joint Lab Environm Simulat &amp;amp;amp; Pollut Con, Beijing 100871, Peoples R ChinaMinist Educ, Int Joint Lab Reg Pollut Control, Beijing 100816, Peoples R ChinaNanjing Univ Informat Sci &amp;amp;amp; Technol, Collaborat Innovat Ctr Atmospher Environm &amp;amp;amp; Equip, Nanjing 210044, Peoples R ChinaShanghai Acad Environm Sci, State Environm Protect Key Lab Format &amp;amp;amp; Prevent U, Shanghai 200233, Peoples R ChinaPeking Univ, Sch Phys, Dept Atmospher &amp;amp;amp; Ocean Sci, Beijing 100871, Peoples R China</style></auth-address></record></records></xml>
