Subject:
FKB/WACR/M1 - Chaff released in Murg valley
DataStreams:fkbwacrM1.b1, fkbwacrM1.00, fkbwacrspecmomM1.00
Description:
As part of the research activities associated with the COPS field campaign, the research 
center at Karlsruhe released aluminum chaff (2.5 cm in length) in the Murg Valley in order 
to study atmospheric diffusion.  It is possible that some of this chaff drifted over the 
AMF site and thus may have influenced the radar observations (as spurious echos). 

20070817 Comment from WACR Mentor, Kevin Widener:
I reviewed the data from the two chaff releases and I'm unable to see any effect in either 
co-polar or cross-polar backscatter signals.  I also looked at the MPL and ceilometer 
and could not see anything that might be chaff. {Editors note: The DQR quality color was 
changed to "Transparent".}
Suggestions: 
Users should be aware of the chaff release event when using these reflectivity data.
