Most of the current research is geared towards modeling, measuring, and predicting the aerosol formation caused by waves breaking at sea. What purpose do these models serve apart from the exchange of gases in aquatic environments?
The scatterring produced by gases and aerosols in the atmosphere are very important for remote sensing techniques in the visible and near infrared regions. Aerosol particles visible in satellite imagery can also be used to study dust storms, wildfire smoke, volcanic ash and urban pollution dispersion. Aerosols also influence the earth radiative heat budget and are one uncertainty in studies prediction global climate change. That´s is a very short answer to your question. The are several books about atmospheric aerosols. Ex: http://www.amazon.com/dp/3540262636/ref=rdr_ext_tmb
