A transportable scanning multiwavelength lidar has been installed for the independent and simultaneous determination of the particle backscatter coefficient at 6 wavelengths between 355 and 1064 nm and of the particle extinction coefficient at 355 and 532 nm. The physical particle parameters including the complex refractive index are retrieved from the optical data by an inversion scheme based on the Tikhonov's regularization technique. The optical and physical parameter sets serve as input in radiative transfer calculations to estimate the radiative forcing of the particles at the top of the atmosphere and at the surface. Quite different particle properties could be observed during the Aerosol Characterization Experiment (Portugal, 1997), the Lindenberger Aerosol Experiment (Germany, 1998) and the Indian Ocean Experiment (Maldives, 1999-2000). We present measurement examples which demonstrates this approach of comprehensive aerosol characterization.
