ABSTRACTAccording to the Earth Observatory dust storms are considered to be natural hazards, which affect the ecosystem. The main aim of this study is to analyse the desert dust transport and local dust contributions in Turkey by using the BSC-DREAM8b model which runs at Turkish State Meteorological Service besides satellite and ground-based observations. With this main aim, efficiency of the model were analysed with some test experiments. In this context, the study period were selected when the dust outbreak occured. Therefore, the study was focused on the date of 18 April 2012 by investigating Aerosol Index product from OMI sensor and PM10 concentrations from air quality stations which are controlled by the Ministry of Environment and Urban Planning in Turkey. After the meteorological conditions were investigated, Aerosol Optical Depth and Surface Concentration were obtained by using different versions of the BSC-DREAM8b model with some test experiments. All these model outputs were compared to satellite and gound-based data. As a result, dust transport event was analysed in detail with model forecast and satellite data. The existence of local dust sources were detected in the case study period associated with high aerosol optical depth. It was also observed that dusts emitted from these arid sources were better catched by BSC-DREAM8b v1.0 than v2.0. The results obtained show that the local dust storms have to an important contribution in the air quality levels in Turkey as confirmed by the model simulations.
