Subject:	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.
Measurements:	sgpswatspcpE19.a1: Hourly precipitation(precip)

Subject:	SGP/SWATS/E19 - Unrecorded Precipitation
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.

Subject:	SGP/SWATS/E19 - Possible Unrecorded Precipitation
DataStreams:	sgpswatspcpE19.a1
Description:	Instrument failed to record precipitation probably due to maintenance on 20030807 (YYYYMMDD). The last precipitation recorded before this date was at 1433 GMT on 20030730. Although unlikely, it is possible the problem arose between 20030730 and 20030807.

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 Alt: 421m
