RADX Dual-Polarization Applications

KDP, PID and Precipitation Rate Applications

The following applications form a group that handle KDP estimation, particle identification (PID) and precipitation rate estimation.

App	KDP	Z & ZDR Attenuation	NCAR PID	Precip Rate
RadxKdp	:heavy_check_mark:	:heavy_check_mark:	:x:	:x:
RadxPid	:heavy_check_mark:	:heavy_check_mark:	:heavy_check_mark:	:x:
RadxRate	:heavy_check_mark:	:heavy_check_mark:	:heavy_check_mark:	:heavy_check_mark:

Use of shared parameter files

Each of these apps has a main parameter file, which controls file handling, operational modes etc.

The main file in turn points to shared parameter files for specific purposes.

RadxKdp reads in a KDP-specific parameter file.

RadxPid reads in the KDP parameter file, and in addition 2 PID-specific files: (a) the PID overview and (b) the interest maps file that specifies the details of the PID fuzzy logic algorithm.

RadxRate reads in all of the above, plus a file specific to the computation of precip rate.

App	App params file	Kdp-specific params	Pid-specific params	Pid Interest Maps	Rate-specific params
RadxKdp	:heavy_check_mark:	:heavy_check_mark:	:x:	:x:	:x:
RadxPid	:heavy_check_mark:	:heavy_check_mark:	:heavy_check_mark:	:heavy_check_mark:	:x:
RadxRate	:heavy_check_mark:	:heavy_check_mark:	:heavy_check_mark:	:heavy_check_mark:	:heavy_check_mark:
