Sahara-originated dust is the most significant natural source of particulate matter; however, this contribution is still unclear in the Eastern Mediterranean especially in Western Turkey, where significant industrial sources and metropolitan areas are located. The Real-time Air Quality Modeling System (RAQMS) is utilized to explore the possible effects of Saharan dust on high levels of PM10 measured in Turkey. RAQMS model is compared with 118-air quality stations distributed throughout Turkey (81 cities) for April 2008. MODIS aerosol product (MOD04 for Terra and MYD04 for Aqua) is used to see columnar aerosol loading of the atmosphere at 550 nm (Aerosol optical depth (AOD) values found to be between 0.6 and 0.8 during the episode). High-resolution vertical profiles of clouds and aerosols are provided from CALIOP, on board of CALISPO satellite. The results suggest a significant contribution of Sahara dust to high levels of PM10 in Turkey with RAQMS and in situ time series showing similar patterns. The two data sets are found to be in agreement with a correlation of 0.87.
撒哈拉起源的尘埃是最主要的自然颗粒物来源；然而，在东地中海，尤其是在土耳其西部，这种影响仍然不清楚，因为那里有大量的工业源和大都市地区。实时空气质量建模系统（RAQMS）被用来探索撒哈拉尘埃对土耳其测量到的高水平 PM10 的可能影响。RAQMS 模型与 2008 年 4 月分布在土耳其（81 个城市）的 118 个空气质量站进行了比较。使用 MODIS 气溶胶产品（Terra 的 MOD04 和 Aqua 的 MYD04）来观察大气在 550nm 处的柱状气溶胶负荷（在该事件期间发现气溶胶光学深度（AOD）值在 0.6 到 0.8 之间）。CALIPSO 卫星上的 CALIOP 提供了高分辨率的云和气溶胶垂直廓线。结果表明，撒哈拉尘埃对土耳其高水平的 PM10 有显著的贡献，RAQMS 和现场时间序列显示出相似的模式。这两个数据集的相关性为 0.87。
