30 November 2006Simulation studies on clouds and aerosols from spaceborne and ground-based lidars and the methodology for validation
Ground based lidars are widely used all over for the study of physical and optical properties of aerosols and clouds in the
atmosphere. The observed parameters on aerosols and clouds and their dependence on various meteorological parameters
are being studied using the ground based lidars at different laboratories. But the results obtained are mostly applicable to
local / regional particular to the lidar observation site. Space borne lidar is a unique system for observing the global
distribution of aerosols and clouds. It provides vertical profiles of the physical properties of the clouds and aerosols with
global coverage. Such data is useful for the validation of climate models and for process studies related to the climate
change and also for studies on transport of aerosols and pollutants. Retrieval of optical properties of clouds and aerosols
from the data obtained by the space borne lidar is very complex. Currently we are developing algorithms to produce
calibrated data products for space borne and ground based lidars. A software to produce simulated lidar backscatter
profiles applicable to space borne and ground based lidars has been developed, which generates data that matches the
expected performance of the lidars under varying conditions. Output simulated data includes 1064 nm total backscatter
profiles and 532 nm profiles for both the parallel and perpendicular polarization states. This paper describes the
methodology used for inverting the ground based lidar data and the strategy for validating the data which will be
obtained from the proposed space borne lidar to be launched by ISRO.
