Radar composite loop.
The national radar composite is created by gridding each NEXRAD site's
base reflectivity product to a 1km grid.
National precipitation type loop.
The precipitation type product utilizes the hour RUC II grids of
freezing level to estimate the precipitation type associated with
radar reflactivities.
Interesting sites are selected from the gridded mosaic using a
gaussian weight function to determine which radar sites have the
greatest reflectivities near them.
