Analysis of Dust Transport Event via Remote Sensing and Numerical Forecast Model

27068

Dust transports from African deserts cause an intense increase of aerosol concentrations in the tropospheric column and often an increase of particulate matter (PM10) at the ground level. For this reason, they have an important impact on Mediterranean site. The area was selected as the Sahara desert and the eastern Mediterranean, where an intense dust event occurred during the period 6–8 April 2013. As the first step, synoptic analysis of this episode is performed for the period of 7–8 April 2013. Synoptic analysis and satellite based model forecasts showed the Egyptian deserts as dust source region. Dust plumes hovered off the coasts of Egypt on April 7 and spanned Cyprus and the sea’s eastern shoreline the following day, reaching as far north as Turkey. The NMMB/BSC-Dust model captured these high values as good matched with the MODIS on NASA’s Aqua satellite. It was observed that the NMMB/BSC-Dust model produces well predictions for dust transport and can be used for early warnings in Turkey
