  2. 1. Variability and feedbacks in the middle atmosphere

    Author : Maartje Kuilman; Bodil Karlsson; Qiong Zhang; Hauke Schmidt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Middle atmosphere dynamics; noctilucent clouds; solar cycle effects; climate feedbacks; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The importance of the middle atmosphere for the weather and climate on Earth is increasingly realized. Variability and feedback processes in the middle atmosphere need to be better understood and form the subject of this thesis. READ MORE

  4. 2. Observations of water vapour in the middle atmosphere

    Author : Stefan Lossow; Jörg Gumbel; Jacek Stegman; Daniel R. Marsh; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water vapour; mesosphere; stratosphere; dynamics; Odin satellite; limb sounding; microwave; tropics; polar winter; Meteorology; Meteorologi; meteorologi; Meteorology;

    Abstract : Water vapour is the most important greenhouse gas and plays a fundamental role in the climate system and for the chemistry of the Earth's atmosphere. This thesis presents observations of water vapour in the middle atmosphere with a particular focus on the mesosphere. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Noctilucent clouds in a coupled atmosphere

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

    Abstract : 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. READ MORE

  7. 5. Studies of planetary waves in ozone and temperature fields as observed by the Odin satellite in 2002-2007

    Author : Alla Belova; Sheila Kirkwood; Andrew Klekociuk; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; middle atmosphere dynamics; planetary waves; 5-day planetary wave; temperature-ozone relationship; Odin satellite; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap;

    Abstract : The results presented in this PhD thesis are mainly based on measurements collected by the advanced sub-mm radiometer (SMR) aboard the Odin satellite in 2002-2007. The primary data are series of temperature and ozone profiles in the middle atmosphere up to 68 km. READ MORE
