The Copernicus Sentinel-5P satellite detected the sulphur dioxide emissions from the Raikoke eruption,
showing the largest amounts of SO2 since the Nabro 2011 eruption emission.

On 21 June 2019, the circular 2.5 km x 2.0 km island discharged a vast plume of volcanic gases and ash,
between 7 and 15 km into the sky. The thick plume was carried to the east by a cyclone in the North Pacific,
which the Copernicus Sentinel-3 and Sentinel-5P satellites recorded.
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 Centers,
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 October 2016, the development of the SACS system is part of the 3-years H2020 EUNADICS-AV project.
The near-real-time monitoring and detection capability of EUNADICS-AV will be improved with new datasets
and expanded to other airborne hazards than volcanic eruptions.

EUNADICS-AV Project is funded by the European Union's Horizon 2020 research programme
for Societal challenges - smart, green and integrated transport under grant agreement no. 723986.

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.
