Experimental NAM and GFS Banding Diagnostics

Note: The NAM output is hourly through 36hr and then 3-hourly thereafter.
Note2: The new GFS fields use spherepak routines for the geostrophic wind and will have far less topographic contamination compared to the NAM.

Please note that these products are experimental and not official forecasts.
