I don't know much about snow properties at HF, but at Ku-band (13.402 GHz, to be specific), the dielectric properties change a great deal with temperature and moisture content. Ice is not particularl
G'day, During the my time in the Antarctic 1974 through 1976 I observed some ice depth radar work. This involved flying for hours at 50 feet above the snow surface, determined by radar altimeter and
There is snow and there is snow. (Ask a cross country skier.) Dry powder has lots of air in it, which gets partly compacted out after a while. Wet snow has liquid water mixed in, etc. Ken, There are
Especially if it is very cold. The AMSR-E instrument on Aqua (now in orbit as part of the "A-train" of earth observing instruments) is also used to evaluate presence of ice, but it's a microwave radi
Ice doesn't have all that high an epsilon (3.2 according to this reference http://snobear.colorado.edu/Markw/SnowHydro/dielectric_const.html)... Liquid water is really high (being a liquid and polar

I can tell you that for my station here in Seattle, I notice significantly improved radiation when we get heavy snow, mainly because it is such a pain to drive so I just end up staying home and opera
