Abstract

Aerosols hygroscopicity and CCN activity in coastal area is influenced by continental-marine air interaction, probably exerting a profound climate effect. In this study, combining field measurement at a coastal site in Shenzhen with a back trajectory model, we have identified an externally-mixed sea salt mode in accumulated particles, where the hygroscopic parameter (κ) ranges from 0.97 to 1.14. The sea salt mode, however, was not observed for ultrafine particles in nucleation/Aitken modes. Nonetheless, the.

期刊介绍： The journal publishes scientific papers (research papers, review articles, letters and notes) dealing with the part of the atmosphere where meteorological events occur. Attention is given to all processes extending from the earth surface to the tropopause, but special emphasis continues to be devoted to the physics of clouds, mesoscale meteorology and air pollution, i.e. atmospheric aerosols; microphysical processes; cloud dynamics and thermodynamics; numerical simulation, climatology, climate change and weather modification.
