We revisited an empirical relationship between the integrated volume depolar-
ization ratio, oacc, and the effective multiple scattering factor, -n, on the basis of Monte
Carlo simulations of spaceborne lidar backscatter associated with homogeneous wa-
ter 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, oacc, and the layer integrated attenuated
backscatter, -n, 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.
