  2. 1. Application of Passive DOAS using Scattered Sunlight for quantification of gas emissions from anthropogenic and volcanic sources

    Author : Claudia Rivera; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nitrogen dioxide; DOAS; gas emission; sulphur dioxide; volcanic; formaldehyde.; scattered sunlight; anthropogenic;

    Abstract : Monitoring of gas emissions from natural and anthropogenic sources is important due to the negative effects of these emissions on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. READ MORE

  5. 3. Application of DOAS for Studies of Evolving Volcanic Activity in Central America

    Author : Alexander Vladimir Conde Jacobo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RSAM; seismic events; UV-scattered sunlight; gas scrubbing; sulphur dioxide; DOAS;

    Abstract : Volcanic gas emissions play a critical role in understanding the physical processes that drive eruptive activity. Combining gas measurements with other geophysical parameters provides a more accurate description of the changes that occur beneath a volcano. READ MORE

  6. 4. Ultrafast Coherent X-ray Diffractive Nanoimaging

    Author : Filipe R. N. C. Maia; Janos Hajdu; David van der Spoel; Keith Nugent; Uppsala universitet; []
    Keywords : XFEL; Phasing; Image Reconstruction; Single Particle Imaging; Ultrafast Diffraction; X-ray diffraction; Coherent Diffractive Imaging; CXDI;

    Abstract : X-ray lasers are creating unprecedented research opportunities in physics,chemistry and biology. The peak brightness of these lasers exceeds presentsynchrotrons by 1010, the coherence degeneracy parameters exceedsynchrotrons by 109, and the time resolution is 105 times better. READ MORE

  7. 5. 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
