Abstract

The 14 April eruption of Icelandic volcano Eyjafjallajökull sent enormous plumes of thick ash over Europe, disrupting air travel for days. Ansmann et al. report lidar (light detection and ranging) and photometer observations of the ash plume over central Europe. Their measurements, made at Leipzig, Germany, on 16 April and Munich, Germany, on the following day, provide some of the first quantitative data on the optical properties of the plume, which is the thickest volcanic ash plume ever measured.
