Subject:	NSA/MET/C1 - Chilled mirror dew point, vapor pressure, and relative humidity noise
Affected Datastreams:	nsametC1.b1
Description	The chilled mirror hygrometer experienced intermittent periods of noise and adjustment delays after automatic daily self-check. In some cases, relative humidity, dew point, and vapor pressure values take a few hours to stabilize.
Measurements	cmh_rh (CMH relative humidity, calculated) cmh_vapor_pressure (CMH vapor pressure, calculated) cmh_dew_point (CMH dew point)

Subject:	NSA/MET/C1 - Present weather detector offline
Affected Datastreams:	nsametC1.b1
Description	The present weather detector began reporting a hardware error (problem with the rain sensor). The instrument was pulled for repair. Data will remain missing until a replacement is installed.
Measurements	pwd_pw_code_15min (PWD 15 minute present weather code) pwd_pw_code_1hr (PWD 1 hour present weather code) pwd_precip_rate_mean_1min (PWD 1 minute mean precipitation rate) pwd_pw_code_inst (PWD instantaneous present weather code) pwd_err_code (PWD alarm) pwd_mean_vis_10min (PWD 10 minute mean visibility) pwd_cumul_snow (PWD cumulative snow) pwd_mean_vis_1min (PWD 1 minute mean visibility) pwd_cumul_rain (PWD cumulative liquid precipitation)
