NSA/MET/C1 - Met data incorrect during calibration

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 - PWS calibration

The PWS was undergoing calibration. Any data collected during this time is not 
representative of the atmospheric state.

NSA/MET/C1 - CMH calibration

CMH data missing due to removal of the sensor for annual calibration.

NSA/MET/C1 - 2m RH values incorrect

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.
