		<description><![CDATA[I almost forgot I was collecting this data!  Here is a time-lapse animation of the map at waterwatch.usgs.gov, which is described as &#8220;real-time streamflow compared to historical streamflow for the day of the year.&#8221;  You can see where drought persists, and track the sweep of storms that bring streams out of their banks.  Also interesting [...]]]></description>

		<description><![CDATA[This is a 12-month animation of color-enhanced images from NOAA&#8217;s GOES East geostationary weather satellite.  It covers all of 2009 except for brief periods when my internet connection or my computer were down.  The date and time of each image is at the upper left, if it survives YouTube&#8217;s reencoding of the video.  This [...]]]></description>

		<description><![CDATA[Out, d*mn spot!
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:
