| Zusammenfassung |
| A long-lasting Saharan dust event affected Europe on 18–23 May 2008. Dust
was present in the free troposphere over Greece, in height ranges between
the surface and approximately 4–5 km above sea level. The event was
monitored by ground-based CIMEL sunphotometric and multi-wavelength combined
backscatter/Raman lidar measurements over Athens, Greece. The dust event had
the maximum of its intensity on 20 May. Three-dimensional dust
spatial distribution over Greece on that day is presented through satellite
synergy of passive and active remote sensing using MODIS and CALIPSO data,
respectively. For the period under study, the ground-based measurements are
used to characterize the dust event and evaluate the latest version of the
BSC Dust Regional Atmospheric Modeling (BSC-DREAM) system. Comparisons of
modeled and measured aerosol optical depths over Athens show that the
Saharan dust outbreak is fairly well captured by BSC-DREAM simulations.
Evaluation of BSC-DREAM using Raman lidar measurements on 20
May shows that the model consistently reproduces the dust vertical
distribution over Athens. |
