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.

NSA/MET/C1 - Wind data intermittent
DataStreams:nsametC1.b1, nsatwrC1.b1

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.

NSA/MET/C1 - Met data incorrect during calibration
DataStreams:nsametC1.b1, nsatwrC1.b1
Description:
All met data from the tower booms (temp, RH, winds and derived variables) were incorrect 
due to the booms being lowered from their measurement heights.  Additionally, the 
scaffolding was located directly adjacent to the booms affecting the wind field and the Temp/RH 
data.

NSA/MET/C1 - 2m RH values incorrect
DataStreams:nsametC1.b1, nsatwrC1.b1
Description:
The new t/rh probe installed during annual calibrations and checks began to exhibit 
readings that were biased high compared to the Chilled Mirror Hygrometer.  In high RH 
conditions the sensor would consistently report RH values in excess of 105%.  Comparisons to the 
other tower levels also suggested that the 2m level RH data is suspect.
