European aerosol distributions will be computed with a regional aerosol-chemistry-transport model system for several case studies representing different meteorological situations. The vertical distribution of aerosol properties is important for understanding their effects, but remains currently highly uncertain. Modeled aerosol properties will be evaluated with lidar measurements from the European Aerosol Research Lidar NETwork (EARLINET). Profile measurements of aerosol t) backscatter and - at some stations - aerosol extinction profiles from ground lidar instruments are available since the year 2000. In addition, since 2006 aerosol backscatter information is available from the CALIPSO satellite lidar instrument. Microphysical aerosol properties will be derived by an inversion algorithm applied to multiwavelength extinction and backscatter measurements for approximately 40 profiles from the Leipzig station. These data will be used for a detailed test of the aerosol microphysics in the model. Aerosol radiative forcing will be computed for the case studies, and the influence of the aerosol distributions on atmospheric heating rates and their dynamic effect will be investigated. The project aims at a better understanding of aerosol properties at the European scale.

欧洲的气溶胶分布将用区域气溶胶化学传输模式系统计算，用于代表不同气象情况的若干案例研究。气溶胶特性的垂直分布对于了解其影响很重要，但目前仍高度不确定。模拟的气溶胶特性将通过欧洲气溶胶研究激光雷达网络（EARLINET）的激光雷达测量进行评估。自2000年以来，可以利用地面激光雷达仪器测量气溶胶（t）后向散射和-在某些台站-气溶胶消光剖面。此外，自2006年以来，可从CALIPSO卫星激光雷达仪器获得气溶胶后向散射信息。微物理气溶胶特性将通过应用于莱比锡站约40个剖面的多波长消光和反向散射测量的反演算法得出。这些数据将用于模式中气溶胶微物理的详细测试。将计算气溶胶辐射强迫的案例研究，气溶胶分布对大气加热率的影响和动力效应将进行调查。该项目旨在更好地了解欧洲范围内的气溶胶特性。
