英国气象局完成了10个激光雷达(紫外线拉曼和去偏振)的部署，每个雷达都配有太阳光度计(偏振型)，为VAAC伦敦提供对英国上空火山灰的定量监测。激光雷达近乎实时地提供距离校正信号和体积去偏振率。太阳光谱仪提供气溶胶光学厚度、埃斯特罗姆指数和线偏振度。对撒哈拉尘埃事件(作为火山灰的替代品)进行了个案研究分析。
The Met Office completed the deployment of ten lidars (UV Raman and depolarization), each accompanied by a sunphotometer (polarized model), to provide quantitative monitoring of volcanic ash over UK for VAAC London. The lidars provide range corrected signal and volume depolarization ratio in near-real time. The sunphotometers deliver aerosol optical depth, Angstrom exponent and degree of linear polarization. Case study analyses of Saharan dust events (as a proxy for volcanic ash) are presented.
