Classification
(HydroClass)
parameter.
There are several possible classification schemes. The choice is made in
the dpolapp_*-band.conf file, where * is C (for C-band radars)
and S (for S-band radars).
The legacy Meteo classifications (up to IRIS/RDA 8.12.6) are:
0
No measurement available
1
Non-meteorological target
2
Rain
3
Wet snow
4

6

Higher bits of the HCLASS data fields may contain results from further
methods of
classification. See sig_data_types.h and HCLASS data
description in IRIS Programming Guide.
