Subject:	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.

Subject:	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.

Subject:	NSA/MET/C1 - PWS calibration
DataStreams:	nsametC1.b1
Description:	The PWS was undergoing calibration. Any data collected during this time is not representative of the atmospheric state.

Subject:	NSA/MET/C1 - CMH calibration
DataStreams:	nsametC1.b1
Description:	CMH data missing due to removal of the sensor for annual calibration.
Measurements:	nsametC1.b1: cmh_dew_point qc_cmh_dew_point qc_cmh_rh cmh_temp cmh_vapor_pressure qc_cmh_vapor_pressure qc_cmh_sat_vapor_pressure qc_cmh_temp cmh_sat_vapor_pressure cmh_rh

Subject:	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.

Subject:	NSA/MET/C2 - CMH Data Incorrect During Maintenance
DataStreams:	nsametC2.b1
Description:	Data was incorrect as the CMH was offline and undergoing maintenance.
Measurements:	nsametC2.b1: qc_cmh_vapor_pressure cmh_sat_vapor_pressure qc_cmh_rh qc_cmh_dew_point cmh_rh qc_cmh_temp cmh_dew_point cmh_temp qc_cmh_sat_vapor_pressure cmh_vapor_pressure
