RadxEvad reads in Doppler data from a polar radar file, computes volumetric VAD (VVP) winds and writes them out to NetCDF.

= Running RadxEvad =
To check all command line options for RadxEvad, including debugging options and file paths, the typical '-h' flag can be invoked:

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

Likewise, to obtain the default parameter file, use the following command:

<code lang="bash">/path/to/lrose/install/bin/RadxEvad -print_params > RadxEvad.params</code>
