| Zusammenfassung |
| In passive and active microwave satellite snowfall retrieval algorithms the scattering
properties of frozen hydrometeors as snowflakes and ice crystals at centimeter and
millimeter wavelengths are fundamental. It is still common practice to approximate the
arbitrarily shaped particles as equal volume ice spheres to avoid computationally
intensive scattering calculations, the more so as even the number of possible ice
crystal shapes is enormous - not to mention the proverbial diversity of snowflake
shapes.
In relevant literature it has been reported that the scattering and absorption cross sections
of randomly oriented ice crystals do not depend on the specific particle shape but on the
specific ice volume for size parameters x |
