Getting NEXRAD weather radar archive data

NOAA archives NEXRAD and TDWR radar data.

12000x5400 PNGs are available since 2010 (6000x2400 back to 1995). Our Python program downloads composite reflectivity data rapidly using multiple download threads.

Unfortunately a colormap-data table or function isn’t readily available. Of course it’s inside the NEX2IMG program, but I would have to hack this a bit to extract the function. Another approach would be to use the HSV map to bin the PNG data.
