  2. 1. Dispersion modelling of volcanic emissions

    Author : Adam Dingwell; Rutgersson Anna; David Simpson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dispersion modelling; atmospheric; volcano; gas emissions; volcanic ash; FLEXPART; FLEXPART-WRF; Spridningsmodellering; atmosfär; vulkan; gasutsläpp; vulkanaska; FLEXPART; FLEXPART-WRF; Meteorology; Meteorologi;

    Abstract : Gases and particles released by volcanoes pose a serious hazard to humans and society. Emissions can be transported over long distances before being reduced to harmless concentrations. Knowing which areas are, or will be, exposed to volcanic emissions is an important part inreducing the impact on human health and society. READ MORE

  4. 2. 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

  6. 4. Studies of Volcanic Plumes with Spectroscopic Remote Sensing Techniques

    Author : Santiago Arellano; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Remote Sensing; FTIR; DOAS; Volcanic gas emissions;

    Abstract : Volcanism is a widespread phenomenon on Earth and other planetary bodies. Terrestrial volcanoes are shallow manifestations of deep and complex mechanisms of heat and mass transport and play an important role in the formation and change of the atmosphere and the natural landscape.

  7. 5. Studies of Volcanic Plumes with Remote Spectroscopic Sensing Techniques -DOAS and FTIR measurements on volcanoes of the Network for Observation of Volcanic and Atmospheric Change-

    Author : Santiago Arellano; Chalmers tekniska högskola; []

    Abstract : Volcanism is a rich geodynamical process, closely linked to the origin and ongoing evolution of the lithosphere, atmosphere, hydrosphere and biosphere. Humans have benefited from the resources provided by volcanoes but also been threatened by the dangers of volcanic eruptions, which accurate prediction remains elusive. READ MORE
