  3. 2. Multi-satellite views on mesospheric microphysics and dynamics

    Författare :Lina Broman; Jörg Gumbel; Susanne Benze; Scott Bailey; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polar mesospheric clouds; satellite tomography; remote sensing; cloud microphysics; wave dynamics; mesosphere; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Atmospheric gravity waves of different scales and origins strongly modulate the wind field and temperature structure of the higher parts of the atmosphere. Direct and continuous measurements of these processes are particularly complicated in the mesosphere at about 50 to 100 km height due to the remote location of this region. LÄS MER

  4. 3. Rocket-borne in situ measurements in the middle atmosphere

    Författare :Jonas Hedin; Jörg Gumbel; Markus Rapp; Ove Havnes; Stockholms universitet; []
    Nyckelord :rocket measurements; noctilucent clouds; meteoric smoke; nightglow; mesosphere; aerodynamics; NATURAL SCIENCES; NATURVETENSKAP; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : The Earth's mesosphere and lower thermosphere in the altitude range 50-130 km is a fascinating part of our atmosphere. Complex interactions between radiative, dynamical, microphysical and chemical processes give rise to several prominent phenomena, many of those centred around the mesopause region (80-100 km).

  5. 4. Noctilucent clouds in a coupled atmosphere

    Författare :Bodil Karlsson; Peter Sigray; Jacek Stegman; Scott Bailey; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Noctilucent clouds; atmospheric dynamics; Meteorology; Meteorologi; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : Noctilucent clouds (NLC) at altitudes around 80 km are the highest clouds in our atmosphere. They have been a subject of research ever since their discovery in the late 19th century. This thesis takes an important step towards using NLC as a tool for studying dynamic coupling processes in the atmosphere on a global scale. LÄS MER

  7. 5. Tomographic views of the middle atmosphere from a satellite platform

    Författare :Kristoffer Hultgren; Jörg Gumbel; Christian von Savigny; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atmosphere; Mesosphere; Noctilucent Clouds; Polar Mesospheric Clouds; Tomography; Remote sensing; Odin; OSIRIS; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The middle atmosphere is a very important part of the Earth system. Until recently, we did not realize the importance of the structure of this vaporous shell and of the fundamental role it plays in both creating and sustaining life on the planet. LÄS MER
