Overview

RadxModelQc quality controls Radx-formatted data using a variety of predefined filters.

Prerequesites

The following items are required:

• Radar data (any Radx supported format, e.g., cfradial)

Parameter file

RadxModelQc uses one parameter file that includes input/output directories and filters.

Ensure file is up to date

To obtain the default parameter file, use the following command:

/path/to/lrose/install/bin/RadxModelQc -print_params > param_file_name

If you already have a parameter file and simply want to check for (and add) updated parameters while retaining current parameters, use the following command:

/path/to/lrose/install/bin/RadxModelQc -params orig_param_file_name -print_params > new_param_file_name

Important parameters

Filters to apply

• fixed_const: fixed constant strings interpreted by user functions
• volume_before_filter: volume filters applied before the sweep filters; all filters available can be viewed with the -print_operators flag
• filter: filters to apply to sweeps; all filters available can be viewed with the -print_operators flag
• ray_filter: filters to apply to individual rays; all filters available can be viewed with the -print_operators flag
• volume_after_filter: volume filters applied after the sweep filters

RadxApp

• mode: determines if the program waits for new files (REALTIME), moves through start and end times specified on the command line (ARCHIVE), or moves through list of files specified on the command line (FILELIST)
• trigger_url: oath to trigger off of
• output_url: names of parameter files for output paths

Once your parameter file is complete, use a command similar to the following to run the application:

/path/to/lrose/install/bin/RadxModelQc -params param_file_name

The user can also specify the location of cfradial files in the following manner:

/path/to/lrose/install/bin/RadxModelQc -f /path/to/cfradial/files/ -params param_file_name
