Description:
<p><em>The European Space Agency project </em>Satellite Monitoring of Ash and Sulphur Dioxide for the mitigation of Aviation Hazards<em>, was introduced after the eruption of the Icelandic volcano Eyjafjallajökull in the spring of 2010 to facilitate the development of an optimal End-to-End System for Volcanic Ash Plume Monitoring and Prediction. The Eyjafjallajökull plume drifted towards Europe and caused major disruptions of European air traffic for several weeks affecting the everyday life of millions of people. The limitations in the volcanic plume monitoring and prediction capabilities gave birth to this observational system which is based on comprehensive satellite-derived ash plume and sulphur dioxide [SO<sub>2</sub>] level estimates, as well as a widespread validation using supplementary satellite, aircraft and ground-based measurements. </em><em>The validation of volcanic total column SO<sub>2</sub> measured by GOME-2/MetopA and IASI/MetopA are shown before, during and after the Eyjafjallajökull 2010 eruptions as well as for the 2011 Grimsvötn eruption. Co-located ground-based Brewer Spectrophotometer data extracted from the World Ozone and Ultraviolet Radiation Data Centre are also compared to the different satellite estimates</em></p>
