Abstract

The use of NRL high power 94 GHz WARLOC radar to image and measured the correlation function of the reflectivity of high altitude cirrus clouds was discussed. The cloud reflectivity had a speckle pattern which indicates that the cloud reflectivity governed at least in part by stochastic processes. The results from correlation functions show an isotropy at the smallest scales, with fluctuations correlated over about three times longer distances horizontally than vertically. It was also observed that, for the particular cloud, both horizontally and vertically, outer scale processes tends to increase the correlation, and also that the correlation function at long length was wave like vertically, but not horizontally.
