Rammesonde
Also: Ram Penetrometer, Ram Profile, Ram Resistance
A cone penetrometer driven vertically into the snowpack by a weighted hammer on a rule guide rod.
A graphical profile that exhibits ram resistance with depth is called a Ram Profile.
The ram resistance is an index of the relative hardness of snow as measured by a rammesonde. R=nHf/P, where n=number of blows, f=vertical fall height of the hammer, H=weight of the hammer and guide rod, and P=penetration depth.
