Subject:	NSA/MET/C1 - Temp/RH/wind data questionable
DataStreams:	nsametC1.b1, nsatwrC1.b1
Description:	New wind sensors and new T/RH probes were being installed during this time period. The tower booms were lowered and much of the data collected were not at listed heights nor were the data accurate due to configurations during install.

Subject:	NSA/MET/C1 - Wind data intermittent
DataStreams:	nsametC1.b1, nsatwrC1.b1
Description:	There was a loose wire on the serial data multiplexer causing the wind data to become missing during high wind situations. The high winds caused the enclosure to vibrate making the connection intermittent.
