The "Mouthful" Volcano continues to create havoc in Europe

Eyjafjallajökull which Patricia has nominated as the tongue twister of the 21st Century continues to erupt and stream ash towards Europe. Jill has pointed out that the volcano has a nickname "Eyjafjöll" which give you a Scottish mnemonic "Aye, ya fool".

The MODIS composite from the FAS subsets that I pulled into Google Earth show broad areas of haze west of Ireland and in the North Sea.

The World Meteorological Organization's Global Atmosphere Watch has encouraged a large number of list communications on the position of the ash cloud. GAW's Aerosol Lidar Network (GALION) stations in Europe are part of the Earlinet network. Show below are cross-sections of the ash plume over Munich, Germany, and Cabauw in the Netherlands. The plume is at a 2-3 km height over northern Europe.

Over France, the Paliseau station shows a similar layer but a higher cloud of ash which was seen in the backscatter and in the depolarization channel of the lidar (this shows that the ash is non-spherical in morphology).
