  2. 21. 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

  4. 22. The impact of mesospheric dynamics and chemistry on key chemical species: 20 years of Odin/SMR satellite observations

    Author : Francesco Grieco; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mesosphere; energetic particle precipitation; H2O; NO; atmospheric solar tides; microwave limb sounding; CO;

    Abstract : Coupling mechanisms between different atmospheric layers are such that changes in middle atmospheric dynamics and composition have an effect on what happens at lower altitudes and on the climate. There is therefore a need to extend climate models to include higher altitudes and to perform measurements of the middle atmosphere. READ MORE

  5. 23. Optical remote sensing of the middle atmosphere from satellites - DOAS retrievals of O3 and NO2 from Odin/OSIRIS limb-scattering measurements

    Author : Samuel Brohede; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : .... READ MORE

  6. 24. Observations and analysis of water in molecular outflows and shocks

    Author : Per Bjerkeli; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; interstellar medium; molecules; jets and outflows; pre-main-sequence; stars; supernova remnants;

    Abstract : This thesis describes observations and analysis of molecular outflows from young stellar objects. The observations using the Odin satellite are described in Paper I, where a non-LTE radiative transfer code has been used to estimate the ortho-water abundance in seven molecular outflows and one super-nova remnant.

  7. 25. Power System Operation Planning and Wind Power Curtailment : Efficient Methods for Power System Scheduling and Integration Studies of Variable Renewable Energy

    Author : Elis Nycander; Lennart Söder; Mehrdad Ghandari; Robert Eriksson; Germán Morales-España; Benjamin Hobbs; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variable renewable energy; wind power integration; production cost model; power-based unit commitment; wind power scenarios; Electrical Engineering; Elektro- och systemteknik;

    Abstract : To reduce carbon dioxide emissions, variable renewable energy (VRE) sources are replacing conventional fossil-based power plants for electricity generation. Due to the variability and uncertainty of weather dependent VRE sources, there can be situations when it is not possible to accommodate all the available VRE production, and VRE sources have to be curtailed.
