TsCalAuto

TsCalAuto analyzes radar calibration data.

Overview

TsCalAuto analyzes radar calibration data.

Prerequesites

The following items are required:

• FMQ data

Parameter files

TsCalAuto uses one parameter file that includes the location of input data, parameters specific to the clutter analysis, and the output directory.

Ensure file is up to date

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

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

Important parameters

Time series - input data

• input_fmq_path: path to time series FMQ

Calibration procedure parameters

• k_squared: complex index of refraction, depends on radar wavelength
• moments_input_dir: directory containing radar data (if not specified on the command line and if mode = REALTIME)
• beamWidthDegH: horizontal 3 dB beam width
• beamWidthDegV: vertical 3 dB beam width
• antGainDbH: horizontal antenna gain (dB)
• antGainDbV: vertical antenna gain (dB)
• systemPhidpDeg: approximate PHIDP value in echo closest to the radar

Output results

• output_dir: path where output will be written

Running TsCalAuto

To check all command line options for TsCalAuto, including debugging options and file paths, type the following command into a terminal.

/path/to/lrose/install/bin/TsCalAuto -h

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

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

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

/path/to/lrose/install/bin/TsCalAuto -f /path/to/calibration/files/ -params param_file_name
