在1998年（LACE）、2006年（SAMUM-1）和2008年（SAMUM-2和EUCAARI）使用德国航天中心研究飞机Falcon进行的四次飞机实地试验期间，进行了机载高光谱分辨率激光雷达和现场测量气溶胶微物理和光学特性。总之，六种不同的气溶胶类型和气溶胶混合物-撒哈拉矿物粉尘，撒哈拉粉尘混合物，加拿大生物质燃烧气溶胶，非洲生物质燃烧混合物，人为污染气溶胶和海洋气溶胶的特性进行了研究。在此基础上，广泛的HSRL数据集，我们提出了一个气溶胶分类方案，也能够识别不同气溶胶类型的混合物。我们计算了混合线，使我们能够确定贡献的气溶胶类型。气溶胶分类方案得到了后向轨迹分析的支持，并通过现场测量进行了验证。我们的研究结果表明，所开发的气溶胶口罩是能够识别复杂的分层与不同的气溶胶类型在整个大气中。
During four aircraft field experiments with the DLR research aircraft Falcon in 1998 (LACE), 2006 (SAMUM-1) and 2008 (SAMUM-2 and EUCAARI), airborne High Spectral Resolution Lidar (HSRL) and in situ measurements of aerosol microphysical and optical properties were performed. Altogether, the properties of six different aerosol types and aerosol mixtures - Saharan mineral dust, Saharan dust mixtures, Canadian biomass burning aerosol, African biomass burning mixture, anthropogenic pollution aerosol, and marine aerosol have been studied. On the basis of this extensive HSRL data set, we present an aerosol classification scheme which is also capable to identify mixtures of different aerosol types. We calculated mixing lines that allowed us to determine the contributing aerosol types. The aerosol classification scheme was supported by backward trajectory analysis and validated with in-situ measurements. Our results demonstrate that the developed aerosol mask is capable to identify complex stratifications with different aerosol types throughout the atmosphere.
