Abstract
Surface aerosol measurements from a moderately populated high mountain valley are interpreted in terms of local wind velocity and meteorology. Diurnal trends are apparent with light winds and especially during wintertime temperature inversions when the concentrations are dominated by local anthropogenic sources. Under conditions of higher wind speeds when the surface concentrations appear to be representative of widespread areas, a seasonal trend is revealed. Cloud condensation nuclei (CCN) concentrations are much higher during the late spring (> 1000 cm−3) than during the winter (< 400 cm−3) but the condensation nuclei (CN) concentrations are not seasonal. The seasonality of the CCN is probably caused by differences in the long range transport of particles from distant California population centers.
