A method of remote measurement of the particle size and density distribution of water droplets has been developed. In this method, the size of droplets is measured from the Mie scattering parameter which is defined as the total-to-backscattering ratio of the laser beam. The water density distribution is obtained by a combination of the Mie scattering parameter and the extinction coefficient of the laser beam.
This method was examined experimentally for the mist generated by an ultrasonic mist generator and applied to clouds containing rain and snow.
Compared with the conventional sampling method, the present method has advantages of remote measurement capability and improvement in accuracy.
