 TC-Diag is run once for each initialization time to produce diagnostics for each user-specified combination of TC tracks and model fields. The user provides track data (such as one or more ATCF a-deck track files), along with track filtering criteria as needed, to select one or more tracks to be processed. The user also provides gridded model data from which diagnostics should be computed. Gridded data can be provided for multiple concurrent storms, multiple models, and/or multiple domains (i.e. parent and nest) in a single run.
 
-TC-Diag first determines the list of valid times that appear in any one of the tracks. For each valid time, it processes all track points for that time. For each track point, it reads the gridded model fields requested in the configuration file and transforms the gridded data to a range-azimuth cylindrical coordinates grid. For each domain, it writes the range-azimuth data to a temporary NetCDF file, as described in :numref:`Contributor's Guide Section %s <tmp_files_tc_diag>`.

 Once the input data have been processed into the temporary NetCDF files, TC-Diag then calls one or more Python diagnostics scripts, as specified in the configuration file, to compute tropical cyclone diagnostic values. The computed diagnostics values are retrieved from the Python script and stored in memory.

 Introduction
 ============
 
-The TC-RMW tool regrids tropical cyclone model data onto a moving range-azimuth grid centered on points along the storm track provided in ATCF format, most likely the adeck generated from the file. The radial grid spacing may be set as a factor of the radius of maximum winds (RMW). If wind fields are specified in the configuration file the radial and tangential wind components will be computed. Any regridding method available in MET can be used to interpolate data on the model output grid to the specified range-azimuth grid. The regridding will be done separately on each vertical level. The model data files must coincide with track points in a user provided ATCF formatted track file.
+The TC-RMW tool regrids tropical cyclone model data onto a moving range-azimuth grid centered on points along the storm track provided in ATCF format, most likely the adeck generated from the file. The radial grid spacing can be defined in kilometers or as a factor of the radius of maximum winds (RMW). The azimuthal grid spacing is defined in degrees counter-clockwise from due east. If wind fields are specified in the configuration file, the radial and tangential wind components will be computed. Any regridding method available in MET can be used to interpolate data on the model output grid to the specified range-azimuth grid. The regridding will be done separately on each vertical level.
