This animation shows the movement of the ash plume from the eruption of the Eyjafjallajoekull glacier in Iceland.
 
The information has been derived from SEVIRI instrument on board the Meteosat weather satellite in combination with a particle dispersion model. This model has been developed at the Norwegian Institute for Air Research in the Department of Atmospheric and Climate Research.

This service was developed within the ESA Data User Element ‘Support to Aviation for Volcanic Ash Avoidance’ with the aim of generating accurate and timely satellite-based information to Volcanic Ash Advisory Centres (VAACs) to assist the aviation community.

Due to the plume large area’s of Northern Europe’s airspace were closed for airtraffic thursday April 15th.

An animation of the plume can be viewed at ESA’s website
