Quicklooks for period following the  Eyjafjallajokull eruption (Updated 26-4-2010)

The layer between 8-10km is a cirrus. The elevated aerosol layer up to 5km originates from Sahara. No volcanic ash observed.

Low clouds present. In between some layers were visible up to 3km originating from Sahara

No volcanic ash observed. Measurements interrupted due to low clouds and strong winds.

The layer between 3-4km should be volcanic ash, as well as the one around 6km. In-between at 4km there was a visible thin cloud affecting the measurements. The layer at 8-10km should be a cirrus cloud.

The layer at between 2-3km should be volcanic ash and is descending into the PBL, while a new one is appearing at 3km after 13:00 UT

There is a cloud at 4km but below that we can still observe an aerosol layer at 3km.

Occasional clouds at 4km. The possible volcanic layer at 2-3km still persists.  Desert dust also predicted for this day
