|SAVAA: Call for Proposal is now open for competitive tender|
|The Invitation To Tender (ITT) on the DUE, "SAVAA - Support to Aviation for Volcanic Ash Avoidance", Ref. AO5780 in the ESA Invitations to Tender, has been published today on EMITS with a closing date of 11 July 2008.|
|The European Space Agency (ESA) hereby invites all interested companies from DUE
participating countries to submit a tender for the SAVAA procurement. If
companies are not yet registered as an ESA bidder, they are invited to obtain
access to EMITS by completing a questionnaire, which can be found at the
indicated URL below, section Registration Request.
Volcanic eruptions may eject large amounts of ash (aerosols) and trace gases such as sulphur dioxide (SO2) into the atmosphere. These ejecta can have considerable impact on the safety of air traffic and on human health. Ground-based monitoring is carried out at only a limited number of volcanoes: most volcanoes are not monitored on a regular basis, in particular the remotely located volcanoes. Global observations of SO2 and aerosols derived from satellite measurements in near-real-time provide therefore useful complementary information to assess possible impacts of volcanic eruptions on air traffic control and public safety.
This project will be built upon existing services being in demonstration phase right now within Europe and the US (e.g. DUE project TEMIS). The service will focus on the timely delivery of SO2 and aerosol data derived from different satellite instruments, such as SCIAMACHY, OMI, GOME-2, AIRS and SEVIRI, to support the activities of Volcanic Ash Advisory Centres (VAAC) worldwide.
