NSA/VCEIL/C1 - Degraded window
DataStreams:nsavceil25kC1.b1
Description:
The ceilometer continuously gave warnings for window contamination because the window had 
deteriorated. Cloud base height detection did not appear to be significantly affected. 
The window conditioner was replaced on 8/11/09 but this did not clear the warning. The 
instrument was replaced.
