EARLINET, the European Aerosol Research Lidar NETwork, established in 2000 is the first coordinated lidar network for tropospheric aerosol study on continental scale. The network activity is based on scheduled measurements, a rigorous quality assurance program addressing both instruments and evaluation algorithms, and a standardised data exchange format. At present, the network includes 26 lidar stations distributed over Europe.

EARLINET performed almost continuous measurements since 15 April 2010 in order to follow the evolution of the volcanic plume generated from the eruption of the Eyjafjallajökull volcano, providing the 4 dimensional distribution of the volcanic ash plume over Europe. A first thin volcanic layer was observed in the evening of 15 April in The Netherlands at about 10 km of altitude. In the morning of April 16, ash plume reached Central Europe (Germany and France) at 5-6 km a.sl.  and at upper altitude (around 8km a.s.l.) on Belarus. In the following days lower altitudes were also interested by the presence of the volcanic ashes. Volcanic plume transport toward South was almost blocked by the Alps until 20 April when Italian EARLINET stations observed for the first time a clear signature of the plume. Part of the plume proceeded its travel across Europe reaching Greece on 21 April. A second event was observed over Portugal and Spain (6 May) and then over Italy on 9 May 2010. Volcanic plume was then observed again over Southern Germany on 11 May 2010.
