TimeHist visualizes the temporal aspects of Titan storms data.


TimeHist provides windows which show the time history, time-height profile, reflectivity distribution and hail metrics for any selected Titan storm.


The following items are required:

  • Titan storm or track files

Parameter file

TimeHist uses one parameter file that determines the display set up. Unlike most LROSE applications, TimeHist uses a key/value model instead of TDRP.

Ensure file is up to date

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

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

Important parameters

Case tracks

  • use_case_tracks: option to use case tracks
  • case_tracks_file_path: path to TITAN case tracks

Colorscale directory

  • colorscale_dir: path where color scales are located

Running TimeHist

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

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

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

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