The decision to propose EVOSS (a downstream service uniquely related to volcanic hazard monitoring) was driven by 9 institutional End Users from the EU, the Caribbean and Africa, with objective technical needs in managing 6 volcano observatories and having responsibility in current major unrests at 11 volcanoes worldwide, some of which in remote areas subjected to complex operational conditions. EVOSS, stems from the unique ensemble of phenomena, parameters and forerunners involved in volcanic unrests, and the need for responses scaled to the vastly variable intensities, durations and extent of possible eruptive activity. It capitalises on results achieved within projects GlobVolcano and PROMOTE of ESA, currently running. Its main goal is to implement the spaceborne support to volcano monitoring capacity by a substantial amount, acting at supra-regional scale and including multi-parameter tracking with temporal resolutions (multispectral EO) and spatial resolutions (Radar EO) hitherto unachieved. EVOSS, is centred on the development or the finalization of advanced data processing techniques for Gas/Ash, Thermal (high-temperature) and Ground deformation, underlain by robust theory and brought seamlessly to the End User for use in surveillance routine and emergency decision. EVOSS was designed for acting from sustained unrest on, with adaptive task scaling up to handing over the surveillance to spaceborne observation during events of outstanding areal impact, that may lead to withdraw personnel from the field or to evacuate the observatory. The integration of space-borne data in groundbased monitoring arrays (if they exist) is done at the local level. In EVOSS, the concept is voluntarily restricted to EU and Africa but can be readily extended globally by exploiting the combined potential of geostationary multispectral and Radar LEO observations, to enhance the quality and speed of the response of Observatories to multi-hazard and trans-national events.
