Aerosol Characteristics in the Marine Boundary Layer Over the Straits of Gibraltar - June 1986
Abstract
Measurements of aerosol characteristics in the marine boundary layer were taken during a two-week cruise through the Straits of Gibraltar. Observations of Aitken nuclei concentration, aerosol size spectra (0.01-100 micron diameter), aerosol composition, visibility (scattering coefficient), optical depth (sun photometry), temperature, humidity, winds and cloud cover were acquired during daylight hours. The data show that surface visibility fluctuations correlate well with particle concentration in the 0.56-1.78 micron size range. Surface relative humidity and particle composition appear to be the factors that control concentration in this size range. These data will be used as ground truth for techniques which retrieve aerosol data from satellites. This experiment was well suited for such an application, since there was little cloud cover to obscure satellite measurements, and comprehensive, consistent aerosol measurements were successfully taken. Keywords: Optical depth, Marine atmospheres, Particle size.
