1. Mechanisms for the Influence from Ice Nucleus Aerosols on Clouds and their Indirect Effects: Cloud Modelling
Sammanfattning : The role of multiple groups of primary biological aerosol particles (PBAPs) as ice nucleating particles (INPs), and of ice formation processes such as time-dependent freezing of various INPs, and various secondary ice production(SIP) mechanisms in overall ice concentration has been evaluated in a range of cloud systems by simulating them numerically with the state-of-the-art ‘Aerosol-Cloud’ (AC) model in a 3D mesoscale domain. Also, the mechanismsof aerosol indirect effects (AIEs) arising from anthropogenic INPs, and the responses to these AIEs from time-dependent INP freezing and SIP processes are investigated in the simulated clouds.

2. Factors influencing emission fluxes and bacterial enrichment in sea spray aerosols : Insights from laboratory and field studies
Sammanfattning : Sea spray aerosol (SSA) is one of the major natural aerosol sources and is produced when wave breaking entrains air into ocean surface water, which subsequently breaks up into bubbles. These bubbles rise to the surface and can scavenge biogenic material. LÄS MER
3. Development and validation of a system for the generation, characterization and subsequent air- liquid interface studies of aerosol particles
Sammanfattning : Exposure to nano-sized and nanostructured aerosol particles with tailored properties are likely to increase in society. Occupational exposure to various kinds of nanostructured aerosol particles such as soot and metal aggregates already exists. LÄS MER
