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)

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.

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.

SGP/RAIN/C1 - Instrument problem
DataStreams:sgprainC1.00, sgprainC1.b1, sgprainauxC1.00, sgprainauxC1.b1
Description:
Instrument has shown very large jumps in accumulated rain during the past week when there 
is no rain or very little rain.  

This is coupled with a known issue that is being worked on with the filtering out of noise 
in the instrument.  This filtering leads to removal of low rain rate data resulting low 
accumulation totals on days with low maximum rain rates (<60 mm/hr)
