Abstract

Second half of April and beginning of May 2010, were remembered by a big trouble in the airplane traffic over Europe, due to the eruption of the volcano Eyjafjallajokull in Iceland. The volcanic ash propagated quickly in the atmosphere traversing most of European countries. Its trajectories were forecasted and observed by many meteorological stations to prevent unintended consequences of the airplane transport The lidar stations of the European lidar network EARLYNET-ASOS [1] performed a large campaign of measurements to identify the position, the height above ground level (AGL) and the thickness of the volcanic aerosols transported in the air. It was an appreciable work to update meteorological forecasting and to study volcanic distribution directions, power and sedimentation in continental scale. As partner in EARLINET-ASOS project, Sofia lidar station performed measurements of the atmospheric aerosol profiling which results where quickly presented on the WEB-page of the Institute of Electronics - BAS [2]. A more detailed discussion and comments concerning only Sofia-lidar measurements of the volcanic dust layers observed over the town we present in this work.
