  1. 1. Aerosol-Cloud-Precipitation Interactions - Studied using combinations of remote sensing and in-situ data

    Författare :Moa Sporre; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; clouds; aerosol particles; climate; precipitation; satellite data; Fysicumarkivet A:2016:Sporre;

    Sammanfattning : Cloud droplets never form in the atmosphere without a seed in the form of an aerosol particle. Changes in number concentrations of aerosol particles in the atmosphere can therefore affect the number of droplets in a cloud. LÄS MER

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

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Författare :Henrik Grythe; Johan Ström; Krejci Radovan; Bo Gustafsson; Lars Ahlm; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine aerosol; Applied Environmental Science; tillämpad miljövetenskap;

    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

    Sammanfattning : Today, the growing and aging population, and the rise of new global threats on human health puts an increasing demand on the healthcare system and calls for preventive actions. To make existing medical treatments more efficient and widely accessible and to prevent the emergence of new threats such as drug-resistant bacteria, improved diagnostic technologies are needed.

  4. 4. On the lifecycle of aerosol particles Sources and dispersion over Scandinavia

    Detta är en avhandling från Stockholm : Meteorologiska institutionen (MISU)

    Författare :Peter Tunved; Hans-Christen Hansson; Johan Ström; Douglas Nilsson; Urs Baltensperger; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosols; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi;

    Sammanfattning : Aerosol particles are likely important contributors to our future climate. Further, during recent years, effects on human health arising from emissions of particulate material have gained increasing attention. LÄS MER

  5. 5. Influence of solar activity and environment on 10Be in recent natural archives

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ann-Marie Berggren; Ala Aldahan; Göran Possnert; Anne Hormes; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmogenic isotopes; beryllium; ice cores; varved lake sediments; accelerator mass spectrometry; co-precipitation; NATURAL SCIENCES Earth sciences Exogenous earth sciences Quaternary geology; NATURVETENSKAP Geovetenskap Exogen geovetenskap Kvartärgeologi;

    Sammanfattning : Understanding the link between the Sun and climate is vital in the current incidence of global climate change, and 10Be in natural archives constitutes an excellent tracer for this purpose. As cosmic rays enter the atmosphere, cosmogenic isotopes like 10Be and 14C are formed. LÄS MER
