Subject:	SGP/DISDROMETER/C1 - False reports of precip
DataStreams:	sgpdisdrometerC1.b1
Description:	A number of days during this period show indications of rain on dry days. This occurred during windy periods when vibrations of the splash guard resulted in many small drops being recorded. The splash guard has been removed and the Instrument Handbook has been updated with a larger section describing this issue (Section 5.3 on known problems).
Measurements:	sgpdisdrometerC1.b1: Precipitation(precip_dis) d_max nd Rainfall rate(rain_rate) liq_water num_drop n_0

Subject:	SGP/DISDROMETER/C1 - Reprocess: Incorrect datestamp
DataStreams:	sgpdisdrometerC1.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/DISDROMETER/C1 - Precipitation events not recorded
DataStreams:	sgpdisdrometerC1.b1
Description:	The instrument was not recording precipitation events seen by other co-located instruments.
