SGP/RWP/C1 - Intermittent bad data
DataStreams:sgp915rwpprecipconC1.a1, sgp915rwpwindmomC1.a0, sgp915rwpprecipspecC1.a0,
sgp915rwpprecipmomC1.a0, sgp915rwpwindspecC1.a0
Description:
Intermittent malfunction of RWP, possibly due to poor connections.  Problem did not recur 
after all computer boards were reseated and all electrical connections were 
reestablished.
