“…Their findings reveal that atmospheric aerosols can undergo sudden or gradual deliquescence or exhibit crystalline behavior, especially when aerosols are predominantly composed of ammoniated sulfate or sea salt. The characteristics of ambient aerosols exhibiting deliquescent behavior, along with the corresponding deliquescence relative humidity (DRH) and efflorescence RH (ERH), are influenced by aerosol chemical composition, including the proportions of nitrate (Sun et al., 2018) and secondary organic aerosols (SOA) (Saukko et al., 2015; Wang et al., 2021), as well as other factors such as mixing state (Li et al., 2021; Xiong et al., 2023). Over the past decade, in China, aerosol phase state has become a focal point in atmospheric aerosol research (Kuang et al., 2016; Y. Liu et al., 2017; Qiu et al., 2023; Sun et al., 2018).…”
