Subject:	GAN/RAIN/M1 - Incorrect precipitation data
DataStreams:	ganrainM1.b1
Description:	The weighing bucket rain gauge was not reporting rainfall when other sensors were reporting rainfall, possibly due to configuration or connection problems.
Measurements:	ganrainM1.b1: error_latch Precipitation rate(precip_rate) weight3 total_mm frequency3 frequency2 frequency1 stat_latch total_weight Precipitation, total(precip) weight1 scans_per_min temp3 weight2 ptemp Model derived 2-meter temperature(temp2) temp1

Subject:	GAN/RAIN/M1 - Precipitation not measured
DataStreams:	ganrainM1.b1
Description:	After maintenance and emptying of the bucket, the data flat-lined at zero due to communications problems.

Subject:	GAN/RAIN/M1 - Noise in sensor 3
DataStreams:	ganrainM1.b1
Description:	Sensor 3 was noisy after data collection resumed. This noise cleared up on its own by 20111212 123000 and the noise will only effect the raw data. The ingest which produces the b1 version of the data removes the noise.
Measurements:	ganrainM1.b1: frequency3 total_weight Precipitation rate(precip_rate) Precipitation, total(precip) weight3
