Subject:	AWR/MET/M1 - PWD Incorrect
DataStreams:	awrmetM1.b1
Description:	The PWD was reporting errors during the setup period and was reporting large amounts of precipitation.

Start Date	Start Time	End Date	End Time	Data Quality Metric
12/04/2015	0000	01/19/2016	2359	Suspect

Subject:	AWR/LDIS/MET/S1 - Precipitation Measurements Suspect
DataStreams:	awrmetS1.b1
Description:	Analysis of the PARS2 and the PWD precipitation data indicate that the results are suspect, possibly due to frost/blowing snow. Both instruments reported precipitation for a majority of the days. The TSI movies were reviewed and the days of noticeable precipitation are: 12/26/15 12/31/15 - Potentially just frost buildup 1/6/16 1/11/16 1/12/16 1/13/16
Measurements:	awrmetS1.b1: PWD 1 minute mean precipitation rate(pwd_precip_rate_mean_1min) pwd_cumul_snow pwd_pw_code_15min pwd_cumul_rain PWD 1 minute mean visibility(pwd_mean_vis_1min) pwd_pw_code_inst pwd_pw_code_1hr pwd_err_code PWD 10 minute mean visibility(pwd_mean_vis_10min)

Start Date	Start Time	End Date	End Time	Data Quality Metric
05/06/2016	1104	05/06/2016	2338	Suspect

Subject:	AWR/MET/M1 - Missing or suspect PWD data due to heavy snow
DataStreams:	awrmetM1.b1
Description:	Heavy snow interfered with the instrument lenses causing backscatter and missing data. Data from the present weather detector during this time is suspect or missing.
Measurements:	awrmetM1.b1: pwd_cumul_rain PWD 1 minute mean precipitation rate(pwd_precip_rate_mean_1min) pwd_pw_code_15min PWD 1 minute mean visibility(pwd_mean_vis_1min) PWD 10 minute mean visibility(pwd_mean_vis_10min) pwd_pw_code_inst pwd_pw_code_1hr pwd_cumul_snow

Start Date	Start Time	End Date	End Time	Data Quality Metric
05/10/2016	1905	05/16/2016	0925	Incorrect

Subject:	AWR/MET/M1 - Probable instrument icing
DataStreams:	awrmetM1.b1
Description:	The temperature and relative humidity sensor behaved suspiciously during this time. Temperature and relative humidity readings did not trend inversely, as expected. Ice buildup on the instrument is the probable cause.
Measurements:	awrmetM1.b1: Temperature mean(temp_mean) Humidity, relative, at 2-m height, 1-min avg(rh_mean) Vapor pressure mean, calculated(vapor_pressure_mean)
