The results of experiments to measure the delay, temporal stretching, attenuation, and spatial spreading of optical pulses in scale model clouds are reported. The model clouds consisted of diiodomethane/water or paraffin oil/water emulsions maintained in a rotating scattering cell to prevent settling of the droplets. The optical pulses were 532-nm, 25-psec duration pulses generated by a frequency-doubled passively mode-locked Nd:YAG laser and were detected with a 10-psec resolution streak camera. The measurements of the delay in the mean arrival time of the pulses due to multiple scattering are the first measured directly.
