1995 integrated monitoring study: fog measurements in the northern san joaquin valley-preliminary results

摘要

Vertical gradients in fog chemistry and phsics were measured from a 430 m television broadcast tower in the nothern San Joaquin Valley near Walnut Grove, California. Fog was collected on the ground and at two elevations on the tower using Caltech Active Strand Cloudwater COllectors Version 2 (CASCC2). Work was conducted as part of the 1995 Integrated Monitoring Study (IMS95). Results will be used to evaluate the need to make measurements aloft in future regional studies of fog processing of atmospheric particles and for testing whether vertically resolved fog models provide realistic simulations of fog physics and chemistry above the ground.
