  1. 1. Satellite measurements of upper tropospheric water

    Författare :Mattias Ekström; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cloud ice; upper troposphere; microwave; retrieval; the Odin satellite; humidity; limb-sounding;

    Sammanfattning : Water vapour and clouds in the upper troposphere have strong influence on the Earth's climate system. The present uncertainties regarding the distribution and feedback mechanisms of water to a changing climate are today among the greatest limitations for accurate climate predictions. LÄS MER

  2. 2. Techniques for the validation of Odin and ENVISAT satellite data

    Författare :Ashley Jones; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; data assimilation; remote sensing; ozone; Odin; stratosphere; validation; limb sounding; MIPAS; balloon sonde; systematic;

    Sammanfattning : The depletion of ozone from the stratosphere and the impact of global warming have been identified as phenomena caused as a result of anthropogenic activity. Scientists are thus trying to find quicker and more reliable ways to analyse these environmental problems. LÄS MER

  3. 3. Observations of water vapour in the middle atmosphere

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

    Författare :Stefan Lossow; Stockholms universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water vapour; mesosphere; stratosphere; dynamics; Odin satellite; limb sounding; microwave; tropics; polar winter; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; meteorologi; Meteorology;

    Sammanfattning : 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. LÄS MER

  4. 4. Analysis of stratospheric ozone depletion in the Arctic using a data assimilation technique

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

    Författare :Kazutoshi Sagi; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data assimilation; ozone loss; limb sounding; remote sensing; stratosphere;

    Sammanfattning : Serious ozone depletion has been measured every Antarctic spring since the early 80’s. This ozone depletion is considered to be a result of photo chemical reactions and cat- alytic cycles resulting from anthropogenic halogen containing gases. LÄS MER

  5. 5. Decadal analysis of stratospheric ozone depletion using data assimilation and Odin/SMR measurements

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

    Författare :Kazutoshi Sagi; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ozone loss; remote sensing; stratosphere; limb sounding; data assimilation;

    Sammanfattning : Serious ozone depletion has been measured every Antarctic spring since the early 80’s. This ozone depletion is considered to be a result of photo-chemical reactions and catalytic cycles resulting from anthropogenic halogen containing gases. facilitated by the formation of Polar Stratospheric Clouds (PSCs).
