| Zusammenfassung |
| The “Support to Aviation Control Service” (SACS; http://sacs.aeronomie.be) is an
ESA-funded project hosted by the Belgian Institute for Space Aeronomy since 2007. The
service provides near real-time (NRT) global volcanic ash and SO2 observations, as well as
notifications in case of volcanic eruptions (success rate >95% for ash and SO2). SACS is
based on the combined use of UV-visible (OMI, GOME-2 MetOp-A, GOME-2 MetOp-B)
and infrared (AIRS, IASI MetOp-A, IASI MetOp-B) satellite instruments. The SACS service
is primarily designed to support the Volcanic Ash Advisory Centers (VAACs) in their
mandate to gather information on volcanic clouds and give advice to airline and air traffic
control organisations. SACS also serves other users that subscribe to the service, in particular
local volcano observatories, research scientists and airliner pilots. When a volcanic eruption
is detected, SACS issues a warning that takes the form of a notification sent by e-mail to
users. The SACS notification points to a dedicated web page where all relevant
information is available and can be visualised with user-friendly tools. Information
about the volcanic plume height from GOME-2 (MetOp-A and MetOp-B) are also
available.
The strength of a multi-sensor approach relies in the use of satellite data with different
overpasses times, minimising the time-lag for detection and enhancing the reliability of such
alerts. This presentation will give an overview of the SACS service, and of the different
techniques used to detect volcanic plumes (ash, SO2 and plume height). It will also highlight
the strengths and limitations of the service and measurements, and some perspectives. |
