Location configuration file#

The location configuration files describes some parameters that are depending on the specific location of a radar (type of scans we want to measure, radar name, etc ). The location of the weather radar (its position) itself, is instead usually read from the radar metadata directly and it is not necessarily defined in this file. The fields are described in the table below.

Name	Type	Description
RadarName	STRING	Short version name of a C-band radar (i.e., A, D, L, P) or DX50, MXPol for the X-band radars.
RadarRes	STRING	rad4alp radar resolution (H or L). Only necessary if rad4alp (swiss C-band) data is processed.
RadarBeamwidth	FLOAT	Radar antenna beam width [Deg].
DataTypeIDInFiles	STRUCT	Structure of strings defining the mapping between pyrad names and variable names in input files. If not provided it will be expected that the name in the files are the standard py-ART names (defined in the py-ART config file). An example of such a struct could be:
dBZ	STRING	DBZ
ZDR	STRING	ZDR
RhoHV	STRING	RHOHV
PhiDP	STRING	PHIDP
KDP	STRING	KDP
V	STRING	VEL

AntennaGaindB	FLOAT	Antenna gain [dB].
ScanList	STRARR	A list with the scans used for this data processing. Note that the first scan in this list is used as master scan. The master scan must be the first (temporal) scan of the corresponding rainbow task. In case of composite volumes the master scan is usually a PPI and the following are RHIs. If the radar processed is MCH C-band the scan list consists of the radar elevation (i.e., from 001 to 020). All scan names must have a trailing ‘/’ except if rad4alp data is processed.
