Summary

Experiments with a radar of a wave length of 5·05 cm showed that the back-scattering of a spherical ice particle with a diameter of around 2 cm, covered with a shell of spongy ice of a thickness of 1·9 mm and a liquid water content of 25%, is higher than that of an equal sphere of water. But as soon as the total liquid water content was significantly lower, the back-scattering was even lower than the radar echo of a similar ice sphere. These facts are both in contradiction with theoretical calculations ofBattan andHerman [7] on the back-scattering of spongy ice shells. But a good agreement can be obtained with the theoretical calculations of the same authors [13] assuming that the liquid phase of the spongy shell is concentrated in a shell of water around an equivalent solid ice sphere.

A detailed report on these findings will be published later.
