In my opinion, I agree with Ocala. The smoothing on GR is a better presentation, but for my purposes, the smoothing on Nexrad3 is perfectly acceptable. It's not bad as you can tell from Ocala's image. It is definitely better than Storm Predator's in my opinion.....The non-smoothed reflectivity is about the best of any program in my opinion. Plus, Nexrad3 is $40, while GR products are $80, other than GR2A which is $250.
