1. RADAR2_LOCAL_PLT.PY: This program will describe structure of a NexRad
     level II archive file and plot out a field from a NexRad level II
     archive file if desired.  Data downloaded from
     https://www.ncdc.noaa.gov/nexradinv/

2. RADAR2_REMOTE_SAVE.PY: This script will retrieve a Nexrad level II
     file from NCEI NexRad BigData site and save locally in NetCDF or
     Shapefile format.  User will define a date, time and output_type
     as input parameters Script will retrieve a list of remote files
     for a given data and then find the file closest to desired time.
     Will then retrieve and save in user-defined location.

3. RADAR2_REMOTE_SAVE_PLT.PY: Similar to above but will also create a panel plot
     of up to the 1st 9 sweeps.  These can either be plan or an a map backgnd.
     vars: "Reflectivity","Reflectivity_HI","RadialVelocity","RadialVelocity_HI"

4. RADAR2_THREDDS_PLT.PY: This program will retrieve NexRAD level II
     data remotely using thredds.  Will formulate a query statement
     and list out characteristics...  Will use cartopy to plot out
     desired variable(+sweep) onto screen.  Can create plots of 1 or
     a list of stations.
