The Copernicus Sentinel-5P satellite detects SO2 emissions, as observed for Lewotolo eruption in November 2020.
SO2 height from TROPOMI, developped in the Engage-KTN OPAS project, is now shown on SACS.

On 28 November 2020, a powerful eruption of Lewotolo volcano emitted an SO2/ash plume.
This discharged a plume spread in two ranges of height: 8 and 17 km
as illustrated by IASI sensors onboard MetOp-A adn MetOp-B.

Flight Level (FL) contamination by the volcanic SO2 cloud is developped in the H2020 ALARM project.

The Support to Aviation Control Service (SACS) hosted by the Royal Belgian Institute for Space Aeronomy (BIRA-IASB)
is a project initiated by the European Space Agency (ESA) aiming at supporting the Volcanic Ash Advisory Centres,
like Toulouse VAAC and London VAAC. This is achieved by delivering NEAR REAL-TIME data of SO2 and volcanic ash
derived from satellite UV-vis (OMI, GOME-2A&B, OMPS, TROPOMI) and InfraRed (AIRS, IASI-A, IASI-B) instruments.
The SACS multi-sensors system also includes automatic worldwide detection of volcanic plumes of SO2 and ash and
notifications are sent out by email to interested parties.



From November 2020, the development of the SACS system is part of the 2-years H2020 ALARM project.
The near-real-time monitoring and detection capability of ALARM will be improved with new datasets
and expanded to other hazards than volcanic eruptions.

ALARM project has received funding from the SESAR Joint Undertaking (JU) under grant agreement No 891467.
The JU receives support from the European Union's Horizon 2020 research and innovation programme and
the SESAR JU members other than the Union.

   

 DISCLAIMER:   SACS is a free service that provides ash/SO2 notifications
in case of exceptional concentrations detected by satellite instruments.
The usage of the SACS notifications, whether or not these happen to be
"true" or "false" notifications, is entirely in the hands of the Users.
The SACS developers disclaim liability for any kind of use or misuse
of the SACS information, regardless of the application.
