ERL研究文章|2015-2022年中国近地表NO2浓度加速下降的人为驱动因素
China has experienced accelerated decline in surface NO2 concentrations under the condition of steady reduction in NOx emissions over the past decade, but the reasons for such a nonlinear response in the changes of surface NO2 to reduction in NOx emissions remain unexplored. Through integration of measurements, a chemical transport model (GEOS-Chem), and a random forest (RF) model, we...
