| | | | | | | GOME, ATSR and SAR keep watch over Etna
1 August 2001
| | Italian vulcanologist, Daniele Lodato, checks the eruption frequency from Mount Etna, Europe's largest active volcano, as plumes of smoke spew from one of its openings, near Nicolosi, Sicily, Tuesday, 24 July, 2001. Ashes from the restive Mount Etna continue to rain down and the nearby airport of Catania has had to close several times because of the black volcanic ash and dust on the runway.

| | | | | Scientists of the German Space Agency (DLR) in Oberpfaffenhofen have been monitoring the eruptions of the Etna volcano since mid July using the GOME instrument on board ERS-2. The satellite data show a region southeast of Sicily where the atmosphere is polluted with a concentration of sulphur dioxide up to 10 times higher than normal. To give an idea of the scale, the size of the area of dense concentration is nearly the same as Germany.

The plume of smoke is very evident in the image due to the temperature difference between the smoke and the sea. Interestingly, the smoke is cooler than the sea in much the same way as the wake that follows a jet aircraft.
