FLEXPART simulation and SEVIRI and MODIS Ash Product images for the recent Eyjafjalla eruption
On April the 14th the Eyjafjalla volcano erupted and ejected an immense plume of ash and sulfur up to 11 km into the atmosphere. The west winds transported the plume to Europe where it causes major disruption in flight traffic. A collection of satellite observation and further information on this event can be found at: http://sites.google.com/site/iavceirscweb/eruptions/eyja
As the eruption has stopped now for more than a week we shut down the forecasting system (25.may). It will be started again whenever there are new emissions from the volcano.
With FLEXPART a continuous eruption starting on the 14th of April was simulated. The volcanic tracer's transport was followed over several days. A website showing the forecast of the plume's transport can be found at:
A movie from the above mentioned website can be downloaded here. It shows as well a crossection of the plume at 60 degree latitude. Download at http://zardoz.nilu.no/~flexpart/EYJA/oslo.avi
The volcanic ash is also visible in the SEVIRI ash product originating from METEOSAT 9.

MODIS ash retrievals show the volcanic ash as it is transported westward towards Europe during the first days after the eruption, and later on southward from the volcano. See more figures here.
Amounts of sulfur dioxide (SO2) are also emitted by the Eyjafjalla eruption.
IASI SO2 alerts can be found here.
