On 10 May 2008, an eruption of the Etna volcano on the Italian island of Sicily was measured by the Global Ozone Monitoring Experiment (GOME-2) on EUMETSAT's Metop-A polar-orbiting satellite. The data were evaluated by scientists at the Deutsche Zentrum für Luft- und Raumfahrt (DLR), the German Aerospace Center, in Oberpfaffenhofen, a member of EUMETSAT's Ozone Monitoring and Atmospheric Chemistry Satellite Application Facility.
Etna began erupting on 10 May, belching sulphur dioxide up to 12 km into the atmosphere. GOME-2 measured the sulphur dioxide cloud as it moved over Greece on 11 May, Iran on 13 May and Turkmenistan on 14 May (see three-day composite SO2 product , 11–14 May, source: DLR, Applied Remote Sensing Cluster).
The movement of the SO2 cloud over the Mediterranean Sea towards the Middle East and up to Iran can also be followed in Meteosat-9 Ash RGB products (see greenish cloud patch in the Ash RGB Animation , 10 May 13:00 UTC–12 May 06:00 UTC).
A second eruption of Etna took place on 13 May from an 800-metre crack which opened north-east of Etna's south-eastern crater, emitting large amounts of sulphur dioxide which were measured by GOME-2 and MSG SEVIRI over southern Italy (see images below).
While GOME-2 detected the SO2 cloud in the morning of 14 May, Meteosat-9 'saw' the eruption immediately, i.e. within 15 minutes, at around 09:30 UTC on 13 May. The eruptions were some of the heaviest since 2002 and volcanic ash forced the closure of the nearby Catania airport.
