Abstract

The distribution of backscattered power was computed for three wind profilers in the Colorado network that operated at 50,405, and 915 MHz. Since the backscattered power is a function of fluctuations in the refractivity index, this power distribution also gives the relative distribution of C2n. Similar distributions were found for all three frequencies in the lower troposphere where the atmosphere is often well mixed. But near and above the tropopause the distributions for the three frequencies different, probably because they responded to different processes in the atmosphere.
