Description
Summary:The main objective of the SACS-2/SMASH project is to create an optimal End-to-End System for Volcanic Ash Plume Monitoring and Prediction. This system is based on improved and dedicated satellite-derived ash plume and sulphur dioxide level assessments, as well as an extensive validation using auxiliary satellite, aircraft and ground-based measurements. The focus of the LAP/AUTH satellite data validation activities is to validate SO2 and ash characteristics products provided by different satellite instruments during the following eruptions: 15 to 26 April 2010, Eyjafjallajökull, Iceland. 4 to 20 May 2010, Eyjafjallajökull, Iceland. 21 to 28 May 2011, Grimsvötn, Iceland. The validation was performed on two levels, on the total SO2 column assessment, discussed in length in Section 2, and on the ash plume characteristics, i.e. the aerosol optical depth and, where applicable, the ash plume height, presented in Sections 3, 4 and 5. A short section on satellite-to-satellite inter-comparison is given both in sub-section 2.7 for the SO2 products as well as in Section 6 for all different ash products.
