Characterization of CCN in remote coastal region in East Asia: Ground-based observation at Noto peninsula, Japan

摘要

Atmospheric aerosols can play a significant role in regulating radiative properties and lifetimes of clouds by acting as cloud condensation nuclei (CCN). The atmospheric concentrations of CCN are perturbed by major anthropogenic emission sources. This is particularly true in East Asia and its downwind regions which can be considered by far as one of the global hotspots of anthropogenic aerosols. Despite the regional relevance, there are still few reports on the variations of CCN properties in relation to the distinct monsoon and seasonal climate in the region.
