  1. 1. Studies of Volcanic Influence on Aerosols, Clouds and Climate

    Författare :Johan Friberg; Ergonomi och aerosolteknologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lowermost stratosphere; volcanic aerosol; upper troposphere; sulfurous aerosol; carbonaceous aerosol; ion beam analysis; volcanism; indirect effect; radiative forcing; direct effect; Stratosphere; Fysicumarkivet A:2016:Friberg;

    Sammanfattning : This thesis focuses on the influence of volcanism on the compositions of the aerosols in the upper troposphere (UT) and lowermost stratosphere (LMS), and their direct and indirect impact on climate. Aerosol data were obtained by aircraft-borne sampling, using the CARIBIC (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) platform, and laboratory-based ion beam analysis of aerosol samples at the Lund Ion Beam Analysis Facility (LIBAF).

    Sammanfattning : The aim of this work was to study atmospheric aerosols, focusing on the chemical composition, the morphology and the origin of the aerosol in the upper troposphere and lowermost stratosphere. An aerosol sampler was developed for this purpose. A new method for quantitative analysis of the major components of the aerosol, i.e. LÄS MER
