Hydrometeor Classes

The reference method characterizes membership functions for 11 classes, while the results were interpreted in the scheme of 9 final output classes.

Simplicity was considered advantageous for typical applications, and 5 final classes have been defined as the basis for classification in the current implementation:

• Rain
• Wet Snow
• Dry Snow
• Graupel
• Hail

In order to characterize the precipitation phenomena in realistic fashion, a commonly emerging mixture 'rain and hail' has been modelled with specific MBFs, in addition. Outcomes in this intermediate class are merged into the final output class 'hail'.

Membership functions (MBFs) and rule strengths (RS) have been re-optimized using the new class basis in a dedicated effort, see Customization to Simultaneous Transmission, Simultaneous Receive Mode.
