The LIDAR (laser radar) is an active remote sensing technique, which allows for the altitude-resolved observation of several atmospheric constituents. A typical application is the measurement of the vertically resolved aerosol optical properties. By using aerosol particles as a marker, continuous determination of the mixing layer height (MLH) can also be obtained by LIDAR. Some examples of aerosol extinction coefficient profiles and MLH extracted from a 1-year LIDAR data set collected in Milan (Italy) are discussed and validated against in situ data (from a balloon-borne optical particle counter). Finally a comparison of the observation-based MLH with relevant numerical simulations (mesoscale model MM5) is provided.
激光雷达是一种主动遥感技术，可对多种大气成分进行高度分辨观测。一个典型应用是测量垂直分辨的气溶胶光学特性。通过将气溶胶粒子用作标记物，激光雷达还可连续测定混合层高度（MLH）。本文讨论了从意大利米兰收集的为期1年的激光雷达数据集中提取的气溶胶消光系数剖面和混合层高度的一些示例，并与原位数据（来自气球携带的光学粒子计数器）进行了验证。最后，给出了基于观测的混合层高度与相关数值模拟（中尺度模型MM5）的比较结果。
