Delivering real-time, advanced satellite products and modellingsupport to volcano monitoring and prediction Steve Tait, IPGP Susan Loughlin, BGS-NERC Evoss team, (particularthanks to BGS team)
EVOSS Targets • to assist in VOLCANO CRISIS MANAGEMENT • Particularly to provide real-time observation support to volcano observatories or mandated institutes • When there is little or no ground-based monitoring • Focus from SUSTAINED UNRESTTO ERUPTION • Capacity to deal withSEVERAL CRISES AT ONCE • For LONG LASTING (months to years) and SPATIALLY SCATTERED CRISES • VERY-HIGH TEMPORAL RESOLUTIONis given priority over high spatial resolution, a methodological breakthrough towardsREAL-TIME OPERATIONS • SUSTAINABILITY AND TIMELINESS OF OPERATIONS is a priority
EVOSS User-Driven Objectives • To develop services within the framework of the EU FP7 GMES programme to respond to major volcanic activity • To deliver appropriate EO products in formats that are useful and usable for observatories and other authorities via the Virtual Volcano Observatory web portal • To facilitate integration of EVOSS products in routine monitoring • To appraise the service, interrogate user feedback and suggest service improvements
User Driven • Observatories • Icelandic Meteorological Office, Iceland • Geological Survey of Uganda • Centre d’Etude et Recherche de Djibouti, Djibouti • Geological Survey of Tanzania, Dodoma, Tanzania • ObservatoireVolcanologique de Goma, Congo • ObservatoireVolcanologique du Karthala, Comoros • Addis Ababa Science Faculty, Ethiopia • Seismic Research Centre, University of the West Indies, Trinidad • Montserrat Volcano Observatory, Montserrat • ObservatoireVolcanologique de la Soufrière de Guadeloupe, FWI • ObservatoireVolcanologique de la Montagne Pelée, Martinique FWI • Observatoire Volcanologique du Piton de la Fournaise, Reunion • InstitutoNacional de Meteorologia e Geofìsica, Cabo Verde • Istituto Nazionale di Geofisica e Vulcanologia, Italy • VAAC • Toulouse Volcanic Ash Advisory Centre, France • London Volcanic Ash Advisory Centre, UK • Other agreements • ESA • EUMETSAT • UNOPS
Theatre of EVOSS Operations • 1 Stromboli (Italy) • 2 Etna (Italy) • 3 Jebel Al Tair (Yemen) • 4 MandaHararo (Ethiopia) • 5 Dalafilla (Ethiopia) • 6 Dabbahu (Ethiopia) • 7 Erta Ale (Ethiopia) • 8 Nyiragongo (Congo) * • 9 Nyamulagira (Congo) * • 10 OlDoinyoLengai (Tanzania) • 11 Karthala (Comoros) * • 12 Piton de la Fournaise (Reunion) * • 13 Soufriere Hills (Montserrat) * • *Hi-Res DEM and Ground Deformation service active • Added after start of the project: • Eyjafjallajökull (Iceland) • Grimsvötn (Iceland) • Nabro (Eritrea) • Mt. Cameroon (Cameroon) • Hierro (Canary) • Jebel Zubair (Yemen) Monitored on a regular basis
EVOSS Services • ATMOSPHERIC SERVICES • Sulphur Dioxide by 4 polar orbiting satellites • Volcanic Ash plumes by geostationary SEVIRI, with an additional Operation-and-Research agreement with EUMETSAT • HIGH-TEMPERATURE ANOMALY SERVICES • Fully automated quantitative exploitation of SEVIRI(15-min repetition rate) and automated off-line use of 2 night-time scenes of MODIS for systematic Cal/Valof results in geometrically diverging zones of the SEVIRI ‘disk’ • Porting of the technique to other platforms/sensors (JAMI onboard MTSAT-2) • GROUND DEFORMATION SERVICES • Integrated exploitation of new, X- band SAR platforms COSMO-SkyMEDover volcanic areas • DEM Development of a processing strategy for high-repetition raterapid mapping, generation of fast, very-high quality, PS constrained Digital Elevation Models
Interaction with end-users • Pre-EVOSS user requirements analysis from ESA Globvolcano project • 2010 First users workshop in La Reunion with potential users worldwide including Mexico, DRC, Italy, Ethiopia (users presented their requirements)... • October 2012 First demonstration of the system to users from Europe and the Caribbean (UK) • January 2013 Second demonstration to users from African region (Ethiopia) • June 2013 Third demonstration to users from Geological Survey of Tanzania
Successful demonstration workshops Charlotte Vye-Brown (BGS) and Kay Smith (BGS) delivered all the demonstration workshops. June 2013 at the Geological Survey of Tanzania
Demonstration • A detailed user handbook was produced containing instructions on using the service and details on the product metadata • At the demonstration, users were able to work through the handbook whilst interacting with the system. • BGS staff provided basic instruction in EO methodologies as well as how to use the system.

Updates to users A Newsletter was conceived and keeps users up-to-date with progress.
User feedback • Detailed questionnaires were circulated at the demonstration workshops • Response was overwhelmingly positive with assertions that the service MUST continue! • Concerns about practical issues such as bandwidth availability • Hopes for increased resolution and excitement about Sentinels. • Comprehensive User Feedback is available in an EVOSS report
