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

    Författare :Ashley Jones; Chalmers tekniska högskola; []
    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. 2. Satellite Limb-Scatter Observations of Stratospheric NO2 and O3 -Retrievals, Validation and Applications

    Författare :Samuel Brohede; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; satellite; NO2; Odin; limb-scatter; validation; OSIRIS; stratosphere; remote sensing; O3; retrieval;

    Sammanfattning : Global observations of vertically resolved atmospheric constituents with high temporal and spatial sampling are crucial for various scientific assessments of ozone depletion and climate change. This thesis explains how such data can be retrieved from satellite limb-scatter observations. LÄS MER

  4. 3. 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

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Satellite measurements of upper tropospheric water

    Författare :Mattias Ekström; Chalmers tekniska högskola; []
    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
