  1. 1. Earth's albedo in a changing climate

    Författare :Frida A-M Bender; Henning Rodhe; Annica Ekman; William Collins; Stockholms universitet; []
    Nyckelord :albedo; Earth s radiative budget; cloud properties; climate sensitivity; CMIP3; GCMs; satellite observations; NATURAL SCIENCES; NATURVETENSKAP; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : The albedo is a key parameter in the radiative budget of the Earth and a primary determinant of the planetary temperature and is therefore also central to questions regarding climate stability, climate change and climate sensitivity. Climate models and satellite observations are essential for studying the albedo, and the parameters determining it, on large spatial and temporal scales. LÄS MER

  3. 2. Hygrothermal Simulations of Buildings Concerning Uncertainties of the Future Climate

    Författare :Vahid Nik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould growth; climate change; climate uncertainties; hygrothermal simulation; energy demand;

    Sammanfattning : Global warming and its effects on climate are of great concern. Climate change can affect buildings in different ways, i.e. it can change the energy demand or the moisture durability of buildings in the future. LÄS MER

  4. 3. Microorganisms in indoor environments. A search for health-related measurements

    Författare :Loay Wady; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; bacteriology; virology; Microbiology; schools; microbial markers; MVOCs; building materials; dust; GC MSMS; SPME;

    Sammanfattning : Microorganisms are ubiquitous in indoor air and epidemiological data suggest that inhalation of microbes and/or their products adhered on air–borne dust particles can impair well–being and health. In the present thesis microbial volatile organic compounds (MVOCs) and cellular markers were studied by gas chromatography–mass spectrometry (GC/MS). LÄS MER

  5. 4. Lifecycle of Black Carbon in the Arctic

    Författare :Roxana S. Cremer; Ilona Riipinen; Peter Tunved; Sara Blichner; Hannele Korhonen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Aerosols; Arctic; lifecyle; absorption; Environmental Sciences; miljövetenskap;

    Sammanfattning : This PhD thesis investigates the atmospheric life cycle of Black Carbon (BC) in the Arctic. The Arctic region has been rapidly changing in the last decades and the role of BC aerosols in this is still uncertain. LÄS MER

  7. 5. Hydrological Modeling for Climate Change Impact Assessment : Transferring Large-Scale Information from Global Climate Models to the Catchment Scale

    Författare :Claudia Teutschbein; Jan Seibert; Chris Kilsby; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bias Correction; Climate Change; Climate Models; Ensembles; GCM; HBV; Hydrological Modeling; Precipitation; RCM; Split Sample Test; Streamflow; Sweden; Temperature; Uncertainty; Physical Geography; naturgeografi;

    Sammanfattning : A changing climate can severely perturb regional hydrology and thereby affect human societies and life in general. To assess and simulate such potential hydrological climate change impacts, hydrological models require reliable meteorological variables for current and future climate conditions. LÄS MER
