Several ground-based remote sensing and in-situ instruments were used to investigate the development of the sea-breeze front and its effect on both the optical and physical aerosol properties, the Particulate Matter (PM) content and the tropospheric and near-surface NO₂ concentrations. Most of the instruments belongs to the Boundary-layer Air Quality-analysis Using Network of Instruments (BAQUNIN) supersite, in the urban area of Rome (Italy). Two characteristic sea-breeze patterns were identified: the front days, in which the sea-breeze front develops in a few minutes, and the gentle breeze days, in which the onset of the front is gradual (more than 20 min). In the case of front days, Aerosol Optical Depth (AOD) increases during the onset of the breeze. The Ångström Exponent (AE), tropospheric and near surface NO₂ amounts are almost constant during the day, while the aerosols volume size distribution follows a trimodal distribution. PM_2.5 and PM₁₀ concentrations decrease before the development of the sea-breeze front and then increase. Conversely, during gentle breeze days, AOD and AE do not change significantly. The tropospheric and near surface amount of NO₂, PM_2.5 and PM₁₀ concentrations decrease, suggesting a significant dispersion of pollutants, while the aerosol size distribution shows a trimodal predominance.

使用了几种地面遥感和现场仪器来研究海风锋的形成及其对光学和物理气溶胶特性，颗粒物（PM）含量以及对流层和近地表NO的影响。_2个浓度。大多数仪器属于罗马市区（意大利）的“使用仪器网络进行边界层空气质量分析”（BAQUNIN）超级站点。确定了两个特征性的海风模式：前几天，海风前沿在几分钟内发展；以及微风天，前风逐渐发生（超过20分钟）。在前风的情况下，微风发作时气溶胶光学深度（AOD）会增加。白天，Ångström指数（AE），对流层和近地表NO _2的量几乎恒定，而气溶胶的体积大小分布遵循三峰分布。PM _2.5和PM ₁₀浓度在海风锋形成之前先降低然后再升高。相反，在微风中，AOD和AE不会明显改变。NO ₂，PM _2.5和PM ₁₀浓度的对流层和近地表数量减少，表明污染物的分散性很大，而气溶胶的尺寸分布则显示出三峰为主。
