Mersin is industrialized city with 1.8 million people, a dense port, and different industries. The region is under the influence of mineral dust transport originated from the arid and semi-arid regions, mainly in spring and autumn. Planetary boundary layer height (PBLH) is one of major parameters influencing surface air quality. In this study, the relationship between particulate matters having diameter of 10 μm or less (PM₁₀) and PBLH was investigated in an urban coastal site of Turkey. Relationships between PBLH and the ratios of PM₁₀ to Aerosol Optical Depth (AOD) from MODIS and AERONET were also analyzed to account for transported aerosol that is not concentrated in the planetary boundary layer (PBL). PBL is known as the atmospheric boundary layer (ABL) that is the lowest part of the atmosphere and its behavior is directly influenced by its contact with a planetary surface. The PM₁₀, AOD and PBLH showed a seasonal variability with increasing multiyear seasonal mean values of AOD and PBLH from winter to summer while decreasing trend was found for PM₁₀ over the analyzed site. Paired dataset for MODIS overpass and AERONET observational times shared the same seasonal patterns; however, the magnitude of the seasonal variations differed. The relationship of PBLH–PM₁₀ was weak over the site. Positive correlations observed in spring and summer could be characterized by lower PM₁₀ concentrations and transported aerosols over the region. Compared to PBLH–PM₁₀ correlations, the PM₁₀/AOD ratio increased correlations significantly from −0.18 to −0.43 for MODIS overpass time and −0.18 to −0.30 for AERONET observational time. Improvements were also showed seasonal differences.

梅尔辛是一个拥有180万人，密集的港口和不同行业的工业化城市。该地区受到主要来自春季和秋季的干旱和半干旱地区矿物粉尘运输的影响。行星边界层高度（PBLH）是影响地面空气质量的主要参数之一。在这项研究中，在土耳其的一个城市沿海地区研究了直径为10μm或更小的颗粒物（PM ₁₀）与PBLH之间的关系。PBLH与PM ₁₀比率之间的关系还分析了来自MODIS和AERONET的气溶胶光学深度（AOD），以解释所运输的气溶胶并未集中在行星边界层（PBL）中。PBL被称为大气边界层（ABL），它是大气的最低部分，其行为直接受到其与行星表面的接触的影响。从冬季到夏季，PM ₁₀，AOD和PBLH表现出季节性变化，其AOD和PBLH的多年季节性平均值增加，而在分析地点，PM ₁₀呈下降趋势。MODIS立交桥和AERONET观测时间的配对数据集共享相同的季节模式；但是，季节变化的幅度有所不同。PBLH–PM ₁₀的关系在该站点上很薄弱。在春季和夏季观察到的正相关性可以通过较低的PM ₁₀浓度和在该区域内输送的气溶胶来表征。与PBLH-PM _10的相关性相比，对于MODIS越过时间，PM ₁₀ / AOD比率的相关性显着增加，从-0.18到-0.43，对于AERONET观测时间，相关性从-0.18到-0.30。改善也显示出季节差异。
