Subject:	MAO/CEIL/M1 - Power outage, UPS overload
DataStreams:	maoceilM1.b1
Description:	The UPS was overloaded and caused instrument shutdown. The UPS was replaced.

Subject:	MAO/MET/M1 - Optical rain gauge performance problems
DataStreams:	maometM1.b1
Description:	Condensation inside the optical rain gauge lenses caused false precipitation to be recorded. Sensor replacements also showed signs of false precipitation. User discretion advised.
Measurements:	maometM1.b1: org_precip_rate_min org_precip_rate_max org_precip_rate_std ORG precipitation rate mean(org_precip_rate_mean)
