Recent Climatology and Environmental Impacts of Aerosols Observed from Satellite Data Over Yangtze River Delta Region

Aerosols and clouds are major components of the climate system that have a considerable impact on the radiation budget. They have a significant impact on the hydrological cycle and atmospheric chemistry. The optical and radiative effects of aerosols and clouds on radiative forcing have been studied by the authors. Aerosol optical depth (AOD), absorbing aerosol index (AAI), and vertically distributed aerosol kinds have all been studied to achieve this. This research shows the spatiotemporal variations and climatology of aerosols and clouds over the urban agglomeration domain in East China, specifically the Yangtze River Delta region, from 2002 to 2020. During the study period, the results demonstrated a significant spatiotemporal variation in AOD and AAI values over East China. The study also discusses the impact of fire counts on the urban atmosphere in order to better understand the impact of forest fires and burning. We also showed the vertical structure of aerosol distribution and classification based on CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) data for the period 2007-2020. Finally, data from the CERES (Clouds and the Earth’s Radiant Energy System) satellite across the domain is used to analyse short-wave and long-wave cloud radiative forcing.
