Abstract

The ash layer from the erupted volcano Eyjafjallajökull in Iceland was monitored with the continuously operated MeteoSwiss/EPFL Raman lidar installed at the MeteoSwiss aerological station in Payerne. Aerosol scattering ratio profiles were measured allowing observations of the vertical extent and time evolution of the layer. Ash density profiles were calculated as well using preliminary ash density estimation from an in-situ measurement. These measurements demonstrated the ability of ground based lidars to monitor the vertical distribution of ash layers providing valuable information to the aviation authorities.
