Short summary
Anhydro-saccharides are key organic markers for biomass burning, but their decay rates and driving factors in real ambient environments remain unclear. This study conducted an online field measurement of PM₂.₅-bound saccharides in three eastern Chinese cities. Daytime levoglucosan decay rates were calculated, and the driving factors were investigated using a machine learning model. Findings of this study offers a strong scientific basis to support air pollution management.
