The Influence of Wind on Sea-Salt Aerosol Production and Reduced Visibility

Abstract

Aerosols have been recognized as a major source of uncertainty in climate change models. Wind and precipitation can influence the near surface sea-salt aerosol visibility and satellite derived radiances over the open ocean. Quantifying this role of sea-salt is important for a more complete understanding of aerosols and their effect on climate change (aerosol indirect and direct effects). Here, autonomous ship-based instruments measured meteorological parameters, in-situ and column aerosol light extinction, aerosol size distributions and number concentrations. There was a correlation between wind speed, aerosol production, and light extinction. These relationships must be accounted for in models of radiative transfer and climate for marine regions.
