At this tab, users can specify a mass-dimension (m-D) relation that constrain a PSD that they also specify. A snowing volume inevitably contains a mixture of hydrometeors with diverse shapes and sizes. Since it is impossible to distinguish the shape and size compositions of such a volume with radar or radiometer signal, we usually assume the hydrometeors therein follow certain m-D relation statistically. Thus, for retrieval applications, PSDs constrained by m-D relations are often used to derive ensemble scattering properties of snowing volumes.
