Definition
- Dr.Eberhard and his associates are studying the information on clouds uniquely available from CO2 lidar, which operates in the 9-11 micrometer wavelength range. Techniques are being developed to measure mean (or effective) radius of cloud drop size distributions, and discriminate between water and ice clouds using wavelength-dependent backscatter and extinction. Cloud dynamics using Doppler measurements of particle motions are also being investigated. The coupling of data from this lidar with other sensors, (e.g. mm-wavelength radar), provides other important parameters such as vertical profiles of number concentration, effective radius, and ice water content of cirrus clouds. The phenomenon of zenith-enhanced lidar backscatter from oriented crystals has also been systematically examined. The LIDAR method is used to extract optical depth and emissivity of clouds. (en)
