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.
Suggestions: 
Verify with present weather detector data (pwd_pw_code_inst) that precipitation is 

reported. If a precipitation event is occurring, rain intensity data from the 
maoaosmetS1.a1 data stream can be used for comparison (present weather detector rain rates are not as 
reliable).
Measurements:maometM1.b1:
  • org_precip_rate_std
  • org_precip_rate_min
  • org_precip_rate_max
  • org_precip_rate_mean
