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.
