On the morning of 14. April 2010, the Icelandic volcano Eyjafjallajökull erupted. The plume traveled towards Europe and arrived on April 16., 2010, at 1800 GMT over Munich.

The temporal development of the aerosol layering over Munich

The MULIS-sequence: Range corrected signals („attenuated backscatter“) as overview over the aerosol and cloud distribution over each day. MULIS is the most sophisticated lidar system of the Meteorological Institute of the LMU; shown here are signals of the 1064 nm wavelength. Measurments were performed at Maisach, 25 km north west of Munich.

There are links to larger versions of the image, i.e., with a better temporal resolution, and an image where the position of the main ash-layer is indicated.

In parallel, POLIS-measurements were provided in Maisach and YALIS-measurments in Munich.
