CAMEX-4 LIDAR ATMOSPHERIC SENSING EXPERIMENT (LASE) V1

The CAMEX-4 LIDAR Atmospheric Sensing Experiment (LASE) dataset was collected by the LASE instrument, which is an airborne DIAL (Differential Absorption Lidar) system used to measure water vapor, aerosols, and clouds throughout the troposphere. LASE operates by locking to a strong water vapor line and electronically tuning to any spectral position on the absorption line to choose the suitable absorption cross-section for optimum measurements over a range of water vapor concentrations in the atmosphere. During CAMEX-4, LASE operated from the NASA DC-8 using strong and weak water vapor lines in both the nadir and zenith modes, thereby simultaneously acquiring data below and above the aircraft.

CAMEX-4 激光雷达大气探测实验（LASE）数据集由LASE仪器收集，该仪器是一种机载差分吸收激光雷达（DIAL）系统，用于测量整个对流层中的水汽、气溶胶和云。LASE通过锁定至强水汽线并电子调谐至吸收线上的任何光谱位置，以选择适合的吸收截面，从而在大气中不同水汽浓度范围内进行最佳测量。在CAMEX-4实验期间，LASE利用NASA DC-8飞机，通过强、弱水汽线在正下方和天顶模式中同时工作，从而实现了对飞机下方和上方的数据同时采集。
