  1. 1. Effects of forest fire smoke and volcanism on the stratospheric aerosol

    Författare :Oscar Sandvik; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fjärranalys; Stratosfärsaerosol; Skogsbrandsrök; Vulkanism; CALIOP; FLEXPART; CALIPSO; AIRS; IAGOS-CARIBIC; Remote Sensing; Stratospheric aerosol; Forest fire smoke; Volcanism; CALIOP; FLEXPART; CALIPSO; AIRS; IAGOS-CARIBIC; Fysicumarkivet A:2021:Sandvik;

    Sammanfattning : This thesis explores the stratospheric aerosol through both in-situ measurements and remote sensing. The background stratospheric aerosol is complex and is perturbed by injections of forest fire smoke particles and by particles formed from volcanic SO2. LÄS MER

  3. 2. 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).

  4. 3. Transport of mineral dust into the Arctic : Evaluation of two reanalysis datasets of atmospheric composition

    Författare :Sebastian Böö; Annica M. L. Ekman; Adam Kristensson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arktis; transport; damm; återanalys; reanalys; aerosol; meteorologi; Meteorology;

    Sammanfattning : The main purpose of this thesis is to examine the mineral dust aerosol transport into the Arctic. Two three-dimensional reanalysis datasets of atmospheric composition, the Copernicus Atmosphere Monitoring Service reanalysis (CAMSRA) and the Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), are analyzed with regard to dust transport into the Arctic.
