The Airborne Laser Scanner with Online Waveform Processing (high-accuracy) provides high speed, non-contact data acquisition using a narrow near-infrared laser beam and a fast line scanning mechanism. It was especially designed to measure on snow and ice.lidar provides profiles of the total backscatter at two wavelengths, from which aerosol and cloud properties are derived. It measures also the linear depolarization of the backscattered return, allowing for the discrimination of thermodynamic cloud phase and the identification of the presence of non-spherical aerosol particles. A single laptop computer fully controls the laser, transient recorders, detectors, and data acquisition, including storage, processing, quick-look evaluation and display programs utilizing LabVIEW software. |
