英文摘要	Methanesulfonate, formed in atmospheric oxidation of dimethyl sulfide, is abundant in marine aerosols; however, its hygroscopic properties have not been well understood. In this work, two complementary techniques (a vapor sorption analyzer and a humidity tandem differential mobility analyzer) were employed to investigate hygroscopic properties of CH3SO3Na, CH3SO3K and (CH3SO3)2Ca at different relative humidities (RH). The deliquescence relative humidities were measured to be 70–71% for CH3SO3Na at 15–35 °C, displaying no dependence on temperature. The mass changes at 90% RH, relative to that at <1% RH, were measured to be 4.002 ± 0.053 for CH3SO3Na, 3.479 ± 0.031 for CH3SO3K, and 3.663 ± 0.019 for (CH3SO3)2Ca at 25 °C. CH3SO3Na and CH3SO3K aerosols started to grow at >70% RH, while continuous growth since very low RH (<40%) was observed for (CH3SO3)2Ca aerosols. At room temperature, hygroscopic growth factors at 90% RH were measured to be 1.48 ± 0.02, 1.53 ± 0.04 and 1.65 ± 0.02 for CH3SO3Na, CH3SO3K and (CH3SO3)2Ca aerosols, respectively. © 2020 Elsevier Ltd
