Hygroscopic and optical properties of organic sea salt aerosol and consequences for climate forcing

  title={Hygroscopic and optical properties of organic sea salt aerosol and consequences for climate forcing},
  author={Cynthia A. Randles},
[1] Scattering of incoming solar radiation by sea salt aerosol is strongly dependent on relative humidity (RH) since hygroscopic particles take up water at high RH. Organic compounds may constitute up to 50% of marine aerosol mass in internal mixtures. We used a detailed thermodynamic and optical model to calculate hygroscopic growth and extinction of sea salt aerosol internally mixed with a soluble organic compound. Increasing organic content from 10 to 50% suppresses growth at high RH… CONTINUE READING
