Depolarization Ratio of Clouds Measured by Multiple-field of View Multiple Scattering Polarization Lidar
We have developed the Multiple Field of view Multiple Scattering Polarization Lidar (MFMSPL) system for the study of optically thick low-level clouds. It has 8 telescopes; 4 telescopes for parallel channels and another 4 for perpendicular channels. The MFMSPL is the first lidar system that can measure depolarization ratio for optically thick clouds where multiple scattering is dominant. Field o...
متن کاملObservations of the spectral dependence of linear particle depolarization ratio of aerosols using NASA Langley airborne High Spectral Resolution Lidar
Linear particle depolarization ratio is presented for three case studies from the NASA Langley airborne High Spectral Resolution Lidar-2 (HSRL-2). Particle depolarization ratio from lidar is an indicator of non-spherical particles and is sensitive to the fraction of non-spherical particles and their size. The HSRL-2 instrument measures depolarization at three wavelengths: 355, 532, and 1064 nm....
متن کاملExtinction-to-backscatter ratio of Asian dust observed with high-spectral-resolution lidar and Raman lidar.
Extinction-to-backscatter ratio or lidar ratio is a key parameter in the issue of backscatter-lidar inversions. The lidar ratio of Asian dust was observed with a high-spectral-resolution lidar and a combined Raman elastic-backscatter lidar during the springs of 1998 and 1999. The measured values range from 42 to55 sr in most cases, with a mean of 51 sr. These values are significantly larger tha...
متن کاملLidar measurements of aerosol depolarization ratio
Lidar measurements of the aerosol depolarization ratio provide highly reliable informations to discriminate between spherical and non-spherical particles in the atmosphere and they can help to distinguish between liquid and solid phase aerosols. These measurements can be performed by using a linearly polarized laser source and a hardware configuration of the receiving system including two chann...
متن کاملHigh Spectral Resolution Lidar
Standard lidar systems provide profiles of the attenuated backscatter signal. These can be assembled into images with spatial and temporal resolution adequate for practically all problems of atmospheric research. However, the attenuated backscatter signal is a quantity that is composed of different atmospheric properties. Extremely valuable for an assessment of the state of the atmosphere, they...
