  4. 2. Satellite measurements of upper tropospheric water

    Author : Mattias Ekström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cloud ice; upper troposphere; microwave; retrieval; the Odin satellite; humidity; limb-sounding;

    Abstract : 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. READ MORE

  5. 3. Microwave Radiometric Observations of the Middle Atmosphere: Simulations and Inversions

    Author : Patrick Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric radiative transfer; middle atmosphere; sub-mm; data inversion; profile retrieval; microwaves; limb sounding; ozone; remote sensing;

    Abstract : Two well-known examples of global environmental problems are the ozone depletion and the enhanced greenhouse effect. The importance and the complexity of these questions generate a demand for improved atmospheric observations, and microwave radiometry is an approach which is increasingly important for measurements of the middle atmosphere (10-100 km).

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

    Author : Kazutoshi Sagi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; data assimilation; ozone loss; limb sounding; remote sensing; stratosphere;

    Abstract : 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. READ MORE

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

    Author : Kazutoshi Sagi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ozone loss; remote sensing; stratosphere; limb sounding; data assimilation;

    Abstract : 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).
