The Command word format for Time Series Mode is:
0916-112
FLG Selects flag word output, bits defined as follows:
0 Reflectivity obscured at this bin
1 Velocity obscured at this bin
2 Width obscured at this bin
3 Point clutter detected at this bin
HCLASS Hydrometeor 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 Snow
5 Graupel
6 Hail
Higher bits of the HCLASS data fields may contain results
from further methods of clasification, see sig_data_types.h
and HCLASS data description in the IRIS Programmers
Manual.
SNR Signal-to-Noise ratio on the primary (horizontal) channel.
Uses the same storage
format as Z
Ta Total power in the alternative polarization receive channel
(usually vertical). Uses the same storage format as T.
Za Clutter corrected reflectivity in the alternative polarization
receive channel (usually vertical). Uses the same storage
format as Z.
TSOUT Selects type of data to be output
