SACS2 and SMASH are two ESA-funded projects with main objectives to develop and validate new algorithms for the quantitative retrieval of volcanic ash and SO2 plumes for polar orbiting satellite instruments.

These validation reports are for the Eyjafjallajökull (April 2010) and Grímsvötn (May 2011) test cases,
and the 2011 Etna lava fountains.


The Support to Aviation Control Service (SACS) hosted by the Belgian Institute for Space Aeronomy aims at supporting the Volcanic Ash Advisory Centers, like Toulouse VAAC and London VAAC.

This is achieved by delivering NEAR REAL-TIME data derived from satellite measurements regarding volcanic emissions by UV-visible (OMI, GOME-2A, GOME-2B, OMPS) and InfraRed (AIRS, IASI-A, IASI-B) instruments.

In case of volcanic eruptions, notifications from our multi-sensors system are sent out by email to interested parties.

   

 DISCLAIMER: SACS is a free service that provides SO2 and ash 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.
