由于气溶胶的高度可变性及其对地球气候系统的不同影响，通过卫星测量进行气溶胶类型分类非常重要。未来的地球云、气溶胶和辐射探测器（EarthCARE）卫星使命上的偏振敏感激光雷达测量将提供区分不同气溶胶类型的信息。我们分析了以前的分类方案的基础上，激光雷达测量在532 nm是否适用于EarthCARE测量在355 nm。我们比较协调的激光雷达测量在五个实地实验中进行的两个波长，适应阈值气溶胶分类与未来的星载激光雷达测量和识别的局限性，目前的知识。
Owing to the high variability of aerosols, and their different impact on the Earth's climate system, aerosol type classification from satellite measurements is of high importance. Polarization sensitive lidar measurements on board the future Earth Clouds, Aerosols and Radiation Explorer (EarthCARE) satellite mission will provide information to distinguish different aerosol types. We analyze whether former classification schemes based on lidar measurements at 532nm are applicable to EarthCARE measurements at 355nm. We compare coordinated lidar measurements at both wavelengths performed during five field experiments; adapt thresholds for aerosol classification with future spaceborne lidar measurements and identify limitations of the current state of knowledge.
