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).
