They are microwave radiation sources. Because they are steady, they show up at all ranges in the proper direction. Because they are uniform in intensity, the radar correction for transmission distance causes the estimated reflectivity to increase with range. - John ----- Original Message ----- From: Rob Dale <rdale@xxxxxxxxxxxx> To: Michael James <mjames@xxxxxxxxxxxxxxxx>, gembud@xxxxxxxxxxxxxxxx Sent: Fri, 19 Nov 2010 21:42:53 -0600 (CST) Subject: Re: [gembud] N0R and N0Q Beam Anomalies > composite is unwelcome.

It appears to me to be some sort of interference (either radio or structural)? In any case, they've reported it to the ROC and I haven't heard any explanation or potential fix yet. - Rob _______________________________________________ gembud mailing list gembud@xxxxxxxxxxxxxxxx For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/ -- John W.
