Subject:	SGP/RAIN/C1 - Incorrect precipitation measurements
DataStreams:	sgprainC1.b1
Description:	RAIN TBRG precipitation measurements were significantly lower than accumulated precipitation measured by co-located ORG and MET instruments. This occurred in both light and heavy rain events. The tipping bucket sensor was replaced by a weighing bucket rain gauge.
Measurements:	sgprainC1.b1: Rainfall rate(rain_rate) Precipitation(precip_tbrg)

Subject:	SGP/RAIN/C1 - Missing data
DataStreams:	sgprainC1.b1
Description:	The datalogger connection was disrupted resulting in no data from the weighing bucket rain gauge.

Subject:	SGP/RAIN/C1 - Reprocess: Incorrect datestamp
DataStreams:	sgprainC1.b1
Description:	The datestamp was off by one day for a several day period. Precipitation was only reported for one day during this time period. The data for 20111121 should be reported as 20111122.

Subject:	SGP/RAIN/C1 - Lightning strike
DataStreams:	sgprainC1.b1
Description:	A lightning strike took out the instrument on 6/12. Error_latch and stat_latch flags were tripped and the instrument failed to record precip measured by co-located instruments (e.g. on 6/13). Voltage and other data fields were also very erratic. Instrument was replaced and normal operations resumed on 20110615.
