Analysis of Aerosol Type and Fine- and Coarse-mode Aerosol Direct Radiative Forcing over Regions in East and Southeast Asia Based on AERONET Version 3 Data

Based on the particle linear depolarization ratio (PLDR) and single-scattering albedo (SSA) values obtained for 1020 nm from Aerosol Robotic Network (AERONET) Version 3 Level 2.0 data collected in five regions, namely, northern China, Northwest Asia, Tibetan Plateau, southern China Southeast we classified seven types of aerosol (viz., purely dust, dust-dominated, pollution-dominated, non-absorbing [NA], weakly absorbing [WA], moderately [MA] strongly [SA]) order to assess spatial temporal distributions their constituents radiative effects fine- coarse-mode particles. The fine fraction dominated also played a crucial role Plateau whereas coarse prevailed Asia. Furthermore, fine-mode exhibited its maximum forcing efficiency (110.3 W m–2) during high concentrations SA aerosol. Also, lowest both occurred summer. Finally, various displayed distinct with contributing approximately 20% total Indochinese Peninsula NA WA forming largest percentages Malay Peninsula.
