Abstract:

Lidar measurements of spike returns from clear air are presented. These spikes occur infrequently approximately one in hundred returns but provide returns that are significantly stronger occasionally an order of magnitude larger than the average aerosol backscatter signal. The spike density is 5.7e-3 spikes per meter-cubed for backscattering cross sections estimated to be between 0.003 and 0.80 square-mm per sr. A modified form of the lidar equation which includes returns from large particulates is presented and the probability distribution for the spike magnitudes is derived from five million measurements.
