SGP/SWATS/E19 - Unrecorded Precipitation
DataStreams:sgpswatspcpE19.a1
Description:
During this time period, the tipping bucket was obstructed and prevented from measuring 
precipitation, so any precipitation events will have erroneous measurements of 0. The 
obstruction is probably due to maintenance on 20030807 (YYYYMMDD) which resulted in erroneous 
recorded precipitation (nonzero) at 1450 GMT.

DataStreams:sgpswatspcpE19.b1
Description:
During this time period, the tipping bucket was obstructed and prevented from measuring 
precipitation, so any precipitation events will have erroneous measurements of 0. The 
problem was corrected on 20040205 (YYYYMMDD) with erroneous recorded precipitation (nonzero) 
due to maintenance ending at 1551 GMT.

DataStreams:sgpswatsE19.a1, sgpswatsE19.b1, sgpswatspcpE19.a1
Description:
The latitude, longitude and altitude of the El Reno (E19) site were
incorrectly entered into the ARM database.  The correct location
of the SWATS.E19 instrument is:
   Lat: 35.557N
   Lon: 98.017W

SGP/SWATS/E19 - Rain gauge failure
DataStreams:sgpswatspcpE19.b1
Description:
The tipping-bucket rain gauge for the swatspcp was not functioning correctly.  The rain 
gauge measured no precipitation after 03/29 even though most of the state received some 
precipitation on 04/12-04/13.

The rain gauge was found to have a broken wire and was replaced on 05/21. Rainfall totals 
compare well with the El Reno Oklahoma Mesonet site for the last major rain event on 
05/26.
