SGP/DISDROMETER/C1 - Communication failure
DataStreams:sgpdisdrometerC1.b1
Description:
A communication failure halted data collection over this period of time.  The problem was 
resolved on July 8, 2015 but the proper functioning of the device was not confirmed until 
the rain event of July 16, 2015.
