This paper summarizes measurements of ice depolarization made using a unique facility consisting of a dual-site (7.3-km site spacing), dual-circularly polarized, low-elevation angle (10.7°) receiving system for the SIRIO 11.6-GHz beacon. Significant depolarization (cross-polar discrimination as low as 10 dB) in the absence of attenuation occurred relatively frequently. However, the impact of the ice on the cross-polar discrimination statistics for a 6-month time period was small.
