RadxMesoCyclone estimates the 2-D velocity of a field using optical flow tracking.

=== '''Overview''' ===

RadxMesoCyclone estimates the 2-D velocity of a field in an MDV file by performing optical flow tracking. The optical flow code was provided by Alan Seed of the Australian Bureau or Meteorology.

=== '''Prerequesites''' ===

The following items are required:

* MDV radar files

=== '''Parameter file''' ===

RadxMesoCyclone uses one parameter file that includes the input/output directories and optical flow algorithm parameters.

==== '''Ensure file is up to date''' ====

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

<code lang="bash">/path/to/lrose/install/bin/RadxMesoCyclone -print_params > param_file_name</code>

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:

<code lang="bash">/path/to/lrose/install/bin/RadxMesoCyclone -params orig_param_file_name -print_params > new_param_file_name</code>

==== '''Important parameters''' ====

Parameters

* fixed_const: fixed constants that are interpreted by user functions
* user_data: non-gridded data names
* volume_before_filter: volume filters to apply before the sweep filters; all filters can be viewed with the -print_operators parameter
* filter: sweep filters to apply; all filters can be viewed with the -print_operators parameter
* volume_after_filter: volume filters to apply after the sweep filters

=== '''Running RadxMesoCyclone''' ===

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

<code lang="bash">/path/to/lrose/install/bin/RadxMesoCyclone -h</code>

To see all the filtering options for RadxMesoCyclone, type the following command into a terminal.

<code lang="bash">/path/to/lrose/install/bin/RadxMesoCyclone -print_operators</code>

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

<code lang="bash">/path/to/lrose/install/bin/RadxMesoCyclone -params param_file_name</code>

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

<code lang="bash">/path/to/lrose/install/bin/RadxMesoCyclone -f /path/to/cfradial/files/ -params param_file_name</code>
