Any way to filter metar obs?

[karlwx]

Is there any way to filter metar obs so that the station models do not overlap when plotted, like how they plot in CAVE?

Also, I see how to get the nexrad level 3 data, but I was wondering if there was a way to access the national composites that you can view in CAVE. They don't seem to be listed with the radar sites.

I've figured out how to prevent overlapping station models using metpy's reduce_point_density function. Still looking for an answer to if national radar composites are available!
