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.

NSA/MET/C1 - PWS data missing due to snow impaction
DataStreams:nsametC1.b1
Description:
Blizzard conditions caused the optics to become impacted with snow and ice rendering the 
Present Weather Detector inoperative.

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.
Measurements:nsametC1.b1:
  • Wind speed arithmetic mean(wspd_arith_mean)

  • qc_wspd_vec_mean

NSA/MET/C1 - CMH data missing
DataStreams:nsametC1.b1
Description:
The data from the CMH was missing during these times due to a failing logic board.  The 
board was replaced.
