Subject:	GAN/MWR/M1 - Missing data
DataStreams:	ganmwrlosM1.b1, ganmwrtipM1.a1
Description:	The MWR was unable to communicate with the software. The problem was identified as an incorrect port configuration.

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.

Subject:	GAN/MWR/M1 - Sun in the radiometer's field of view
DataStreams:	ganmwrlosM1.b1, ganmwrtipM1.a1
Description:	Between 10/5 and 10/10 the sun was in the field of view of the radiometer approximately between 7 and 8 AM UTC. The brightness temperature display a rapid increase followed by a rapid decrease during this time.

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.

DataStreams:	ganmwrlosM1.b1, ganmwrtipM1.a1
Description:	Between 12/25 and 2/9 the surface temperature readings were either wrong or missing.
Measurements:	ganmwrlosM1.b1: tkair ganmwrtipM1.a1: tkair
