Properties of snowflakes of different riming degeree and crystal types

The properties of snowflakes such as their size distribution, fall velocity, axial ratio or their orientation when falling are important in modelling precipitation processes or in interpreting returned radar power, especially of polarized radar. However, literature on shape and fall velocity measurements of snowflakes of different crystal type and riming degree is scarce and rely generally on a very small set of snowflakes. This is a direct consequence of the instrumental difficulties in measuring properties of single snowflakes.
