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.
Measurements:	nsametC1.b1: qc_pws_cumul_snow qc_pws_pw_code_15min qc_pws_precip_rate_mean_1min qc_pws_cumul_rain PWS 10 minute mean visibility(pws_vis_mean_10min) pws_err_code qc_pws_vis_mean_1min pws_cumul_rain pws_pw_code_1hr Rain, surface, 1-min avg(pws_precip_rate_mean_1min) pws_cumul_snow pws_pw_code_15min qc_pws_pw_code_inst pws_pw_code_inst qc_pws_pw_code_1hr qc_pws_err_code qc_pws_vis_mean_10min PWS 1 minute mean visibility(pws_vis_mean_1min)

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/C1 - CMH and 10m winds failure
DataStreams:	nsametC1.b1
Description:	At 0513GMT on 1/23 the atmos_pressure and CMH - temp, RH, DP & Sat. VP changed abruptly to unlikely values. The 10m winds failed at 1420GMT. The CMH was repaired on 02/04/2010 at 2254GMT and the 10m winds sensor was replaced on 02/05/2010 at 2100GMT.

Subject:	NSA/MET/C1 - CMH Data Missing
DataStreams:	nsametC1.b1
Description:	The GFCI had tripped causing the CMH to lose power. All CMH variables are missing except CMHRH which reports 100% for the entire time.
