Abstract. The polarization lidar photometer networking (POLIPHON) method introduced to separate coarse-mode and fine-mode
particle properties of Eyjafjallajökull volcanic aerosols in 2010 is extended
to cover Saharan dust events as well. Furthermore, new volcanic dust
observations performed after the Grimsvötn volcanic eruptions in 2011 are
presented. The retrieval of particle mass concentrations requires
mass-specific extinction coefficients. Therefore, a review of recently
published mass-specific extinction coefficients for Saharan dust and volcanic
dust is given. Case studies of four different scenarios corroborate the
applicability of the profiling technique: (a) Saharan dust outbreak to
central Europe, (b) Saharan dust plume mixed with biomass-burning smoke over
Cape Verde, and volcanic aerosol layers originating from (c) the
Eyjafjallajökull eruptions in 2010 and (d) the Grimsvötn eruptions in
2011. Strong differences in the vertical aerosol layering, aerosol mixing,
and optical properties are observed for the different volcanic events.
