  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. Aerosol impacts on subtropical low-level clouds: a satellite and modelling perspective

    Författare :Alejandro Baró Pérez; Annica M.L. Ekman; Frida A.-M. Bender; Abhay Devasthale; Jens Redemann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aerosol-cloud-radiation interactions; cloud microphysics; biomass burning; stratocumulus to cumulus transition; cloud radiative effect; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Complex interactions between aerosols, clouds, and radiation impact Earth's climate. However, several aspects of these interactions remain uncertain, which has led to extensive research over the last decades. LÄS MER

  4. 3. Aerosol-cloud-radiation interactions in global climate models

    Författare :Lena Frey; Frida A.-M. Bender; Gunilla Svensson; Laura Wilcox; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aerosols; clouds; global climate models; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Clouds can reflect, absorb and re-emit radiation, thereby inducing a cooling or warming effect on the climate. However, the response of clouds to a changing climate is highly uncertain and the representation of clouds in state-of-the-art climate models remains a key challenge for future climate projections.

  5. 4. Multiple perspectives on absorbing aerosols over the northern Indian Ocean and Asia

    Författare :Friederike Höpner; Frida Bender; Annica Ekman; Heike Wex; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosols; black carbon; air pollution; South Asia; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Aerosol particles in the atmosphere scatter and absorb solar radiation, and thereby affect the Earth's energy budget, but the magnitude of the overall radiative effect due to aerosol-radiation interactions is uncertain. In particular, the impact of absorbing aerosol particles, mainly black carbon (BC), organic carbon and dust, is not completely understood. LÄS MER

  7. 5. Uncertainties in tropical precipitation and radiative feedbacks under climate change

    Författare :Alejandro Uribe Cortes; Thorsten Mauritsen; Frida Bender; Caroline Muller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; radiative feedback; tropical precipitation; tropical extreme precipitation; climate modeling; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Clouds have a significant impact on climate. They contribute to controlling the planetary energy balance, and the precipitation distribution. Global Climate Models (GCMs) designed to reproduce the state of the climate system, however, have difficulties representing clouds. LÄS MER
