Abstract:
|
Coordinated lidar observations of Saharan dust over Europe are performed in the frame of the EARLINETASOS(2006-2011) project, which comprises 25 stations: 16 Raman lidar stations, including 8 multiwavelength(3+2 station) Raman lidar stations, are used to retrieve the aerosol microphysical properties. Sincethe launch of CALIOP, the two-wavelength lidar on board the CALIPSO satellite (June 2006) our lidarnetwork has been performing correlative aerosol measurements during CALIPSO overpasses over theindividual stations. In our presentation, we report on the correlative measurements obtained during Saharandust intrusions in the period from June 2006 to June 2008. We found that the number of dust events isgenerally greatest in late spring, summer and early autumn periods, mainly in southern and south-easternEurope. A measurement example is presented that was analyzed to show the potential of a ground based lidarnetwork to follow a dust event over a specific study area, in correlation with the CALIOP measurements. Thedust transport over the studied area was simulated by the DREAM forecast model. Cross-section analyses ofCALIOP over the study area were used to assess the model performance for describing and forecasting thevertical and horizontal distribution of the dust field over the Mediterranean. Our preliminary results can beused to reveal the importance of the synergy between the CALIOP measurement and the dust model, assistedby ground-based lidars, for clarifying the overall transport of dust over the European continent. |
