1. 1. Aerosol Exchange between Forests and the Atmosphere : Fluxes over a Tropical and a Boreal Forest

   Författare :Lars Ahlm; Douglas Nilsson; David Fowler; Stockholms universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : The main goal of this thesis was to investigate primary biogenic aerosol emission from the Amazon rain forest through measurements of vertical turbulent aerosol number fluxes. In addition, the particle dry deposition sink has been analysed and quantified, and is also compared with the dry deposition sink at a boreal forest site. LÄS MER

3. 2. Primary Marine Aerosol : Validation of sea spray source functions using observations and transport modeling

   Sammanfattning : Sea spray aerosols (SSA) are an important part of the climate system through their effects on the global radiative budget, both directly as scatterers and absorbers of solar and terrestrial radiation, and indirectly as cloud condensation nuclei (CCN) influencing cloud formation, lifetime and precipitation. In terms of their global mass, SSA is the largest source and has the largest uncertainty of all aerosols. LÄS MER
