The NOAA weather radar images from the National Weather Service have a reflectivity key on the side.  To get rid of the ground clutter &#38; other low intensity noise, just remove the colors from the image corresponding to returns below a certain threshold dBZ.  It sounds like it ought to be simple, [...]]]></description>

		<description><![CDATA[What are those flashing, oscillating spots or blobs on radar animations?  Short answer: noise.  NOAA has the long answer.  In part:
Echoes from surface targets appear in almost all radar reflectivity images. In the immediate area of the radar, &#8220;ground clutter&#8221; generally appears within a radius of 20 nm. This appears as a roughly circular region [...]]]></description>
