“…Quantification of aerosol‐cloud droplet r e relationship is very uncertain due to various influential factors, including the cloud types (Jung et al, ; Zhao, Klein, et al, ), the aerosol properties such as the mixing state (Chen & Penner, ; Nenes et al, ; Wang et al, ), and the meteorology conditions such as the precipitable water vapor (Qiu et al, ; Yuan et al, ), vertical wind shear (Jiang et al, ; Kim et al, ), and lower tropospheric stability (Wang et al, ). Actually, the quantification of aerosol‐cloud r e relationship even varies with the observational platforms such as satellite (Grandey & Stier, ; Li et al, ; Nakajima et al, ; Quaas et al, ; Shao & Liu, , ; Wang et al, ) and ground surface or aircraft (Feingold et al, ; Heymsfield & McFarquhar, ; McComiskey et al, ).…”
