  1. 1. Application of scattered sunlight spectroscopy for quantification of gas emissions from anthropogenic and natural sources

    Författare :Claudia Rivera; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anthropogenic sources; gas emission; volcanoes; sulphur dioxide; DOAS; nitrogen dioxide.; scattered sunlight spectroscopy; natural sources;

    Sammanfattning : Monitoring of gas emissions from natural and anthropogenic sources is of importance due to their negative effects on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. LÄS MER

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

    Författare :Alexander Vladimir Conde Jacobo; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RSAM; seismic events; UV-scattered sunlight; gas scrubbing; sulphur dioxide; DOAS;

    Sammanfattning : 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. LÄS MER
