WxWorx takes the raw data from the NWS and places it through a series of filters in an attempt to remove non-precipitation radar returns--birds, insects, bats, dust and debris, military chaff, anomalous propagation, etc.

It can judge drop size as well as detect false echoes such as ground clutter, anomalous propagation or even birds.
