Subject:	GAN/MET/M1 - Tower lowered and tipped for maintenance
DataStreams:	ganmetM1.b1
Description:	The met tower was lowered for a PIR replacement. All met tower data are questionable during this period.

Subject:	GAN/MET/M1 - Met data questionable
DataStreams:	ganmetM1.b1
Description:	Met data are questionable during this time period as the system was being deployed and in various states of operation.

Subject:	GAN/MET/M1 - Intermittent PWD alarm
DataStreams:	ganmetM1.b1
Description:	Intermittent backscatter alarms were tripping on the PWD suggesting something was blocking (dew) or getting into the measurement path (spider or ants). Problem resolved 10/9 with no clear indication of the cause.

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.
