Effects of multi-charge on aerosol hygroscopicity measurement by a HTDMA [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
The humidified tandem differential mobility analyzer (HTDMA) is widely used to measure the hygroscopic properties of submicron particles. The size-resolved aerosol hygroscopicity κ measured by a HTDMA will be influenced by the contribution of multiply ...

Direct links between hygroscopicity and mixing state of ambient aerosols: estimating particle hygroscopicity from their single-particle mass spectra [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Hygroscopicity plays crucial roles in determining aerosol optical properties and aging processes in the atmosphere. We investigated submicron aerosol hygroscopicity and composition by connecting an aerosol time-of-flight mass spectrometer (ATOFMS) in ...

Cloud droplet activation of secondary organic aerosol is mainly controlled by molecular weight, not water solubility [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Aerosol particles strongly influence global climate by modifying the properties of clouds. An accurate assessment of the aerosol impact on climate requires knowledge of the concentration of cloud condensation nuclei (CCN), a subset of aerosol particles ...
