European Volcano Observatory Space Services (EVOSS) a GMES downstream service for volcanic hazard monitoring

摘要

Volcanic hazards are of major national and international importance, affecting many regions of the globe and potentially having an impact on people both on the ground and in transit in the air. A GMES FP7 'Downstream' Service project called EVOSS (European Volcano Observatory Space Services) is developing a portfolio of services aimed at robust volcanic hazard monitoring. Crucially, EVOSS is being driven by the needs of the End Users rather than by a technology push for space-borne technologies. EVOSS is a three-year project that began in March 2010, and builds on previous projects such as GLOB VOLCANO and PROMOTE. The EVOSS spatial coverage corresponds with the METEOSAT full-disk, centred on Africa and covering the volcanic regions of the Caribbean to the west, and Eastern Africa and the Red Sea to the east. The aim is to provide three services: Thermal Anomalies, Volcanic Emissions (including SO_2 and ash) and Ground Deformation products. The products are derived from a wide range of sensors including SEVIRI (thermal anomalies), SCIAMACHY, OMI, GOME-2, IASI and SEVIRI (atmospheric products) along with COSMO-SkyMed for ground deformation. The first two will be provided in near-real-time while the third will be delivered following an event.
