Wind-driven influences on aerosol light scattering in north-east atlantic air
Ten years (2001-2010) of aerosol light-scattering measurements in N.E. Atlantic marine air are analysed to determine wind-speed related influences on scattering properties. The scattering coefficient and the backscattering coefficient dependency on wind speed (U) was determined for the winter (Low B...
