| Abstract: | We revisited an empirical relationship between the integrated volume depolarization ratio, [delta]acc, and the effective multiple scattering factor, [eta], on the basis of Monte Carlo simulations of spaceborne lidar backscatter associated with homogeneous water clouds. The relationship is found to be sensitive to the extinction coefficient and to the particle size. The layer integrated attenuated backscatter is also obtained. Comparisons made between the simulations and statistics derived relationships of the layer integrated depolarization ratio, [delta]acc, and the layer integrated attenuated backscatter, [eta], based on the measurement by the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellite show that a cloud with a large effective size or a large extinction coefficient has a relatively large integrated backscatter and a cloud with a small effective size or a large extinction coefficient has a large integrated volume depolarization ratio. The present results also show that optically thin water clouds may not obey the empirical relationship derived by Y. X. Hu. and co-authors. |
