An 8.6‐mm‐wavelength, dual‐polarization Doppler radar was operated by the Wave Propagation Laboratory during the Cooperative Convective Precipitation Experiment. The complex cross correlation between the two received polarization channels (left‐ and right‐handed circular) provided information about the degree of common alignment and the scattering properties of the observed hydrometeors. The data show four distinct layers in a lightly precipitating stratiform cloud. These are (1) a subcloud layer consisting of raindrops and some non‐Rayleigh‐scattering graupel particles, (2) a narrow “depolarization band” containing highly non‐Rayleigh particles that are ice and ice‐water mixtures, (3) a main cloud region consisting of small ice particles, and (4) a cloud top region consisting of substantially larger particles than were found in the main cloud.
