Subject:	AWR/AOSMET/M1 - Reprocess: Wind direction offset by 19 degrees
DataStreams:	awraosmetM1.a1
Description:	The wind direction sensor was not installed to true north. GPS calculation confirmed the wind direction was off by 19 degrees, in the positive. The sensor was aligned to true north on 2015-12-23. Prior data will be reprocessed by subtracting 19 degrees from wind direction.
Measurements:	awraosmetM1.a1: Wind direction, relative to true North(WindDirection)

Subject:	AWR/AOSMET/M1 - Installation period
DataStreams:	awraosmetM1.a1
Description:	During this installation period, there were problems with the data messages being sent from the sensor. Some data are missing, and available data experience occasional dropouts.
Measurements:	awraosmetM1.a1: Ambient air temperature(T_Ambient) Wind direction, relative to true North(WindDirection) heater_temp ref_volts Ambient pressure(P_Ambient) heater_volts Rain amount(rain_amount) Wind speed(WindSpeed) Ambient air relative humidity(RH_Ambient) Rain Duration(rain_duration) Rain Intensity(rain_intensity)

Subject:	AWR/AOSMET/M1 - Poor sensitivity to snow
DataStreams:	awraosmetM1.a1
Description:	The sensor plate that detects precipitation impact is not sensitive enough to detect snow (especially light snow). During the AWR deployment, all precipitation measurements from the AOSMETM1 data streams should be carefully considered and compared with colocated precipitation measurements.
Measurements:	awraosmetM1.a1: Rain amount(rain_amount) Rain Duration(rain_duration) Rain Intensity(rain_intensity)

Subject:	AWR/AOSMET/M1 - Icing event
DataStreams:	awraosmetM1.a1
Description:	Significant icing was noted during this time. For most of the period, wind data are missing due to ice buildup on the sensor. Available data for temperature, humidity, pressure, precipitation, and winds during this time should not be used.
Measurements:	awraosmetM1.a1: Ambient air temperature(T_Ambient) Wind direction, relative to true North(WindDirection) Ambient pressure(P_Ambient) Rain amount(rain_amount) Wind speed(WindSpeed) Ambient air relative humidity(RH_Ambient) Rain Duration(rain_duration) Rain Intensity(rain_intensity)
