3D Saharan Dust Variability Over Europe as Seen by CALIPSO
2017
Dust is one of main aerosol types in the atmosphere and plays an important role in modulating climate via a number of complex processes. A 3D multi-year monthly mean climatology of Saharan dust advection
over
Europeis presented under cloud-free conditions, using an area-optimized pure dust CALIPSO product. The product has been developed by applying EARLINET-measured dust lidar ratios and depolarization-based dust discrimination methods. This approach results in a very good agreement when comparing CALIPSO AOD with
AERONETretrievals
over
Europe/North Africa and with the MODIS/Aqua product
overthe Mediterranean. The processing of such purely observational data can provide seasonal patterns of pure Saharan dust transportation towards
Europeand the Atlantic Ocean. The physical and optical properties of the dust layers are identified for several areas near the Saharan sources,
overthe Mediterranean and
overcontinental
Europe.
