Integrating Marine Features into Atmospheric Chemistry Experimental Teaching:Elemental and Spectroscopic Characterization of Dissolved Organic Matter in Atmospheric Wet Deposition of Coastal Cities
Dissolved organic matter(DOM)plays a pivotal role in the marine,terrestrial,and atmospheric systems and is a crucial component of the Earth's biogeochemical cycles.This study focuses on the characteristics of DOM in the atmospheric wet deposition of coastal cities,aiming to explore its practical applications in atmospheric chemistry teaching through elemental and spectroscopic analysis.By integrating theoretical learning and experimental operations,this course design not only helps students understand the scientific significance of DOM but also enhances their experimental skills and data analysis capabilities.
