Subject:
SGP/AOS/C1 - CN counter removed
DataStreams:sgpaosC1.a0
Description:
The AOS condensation particle counter performance degraded to unacceptable
levels and was removed for repair.  

For the first time period: upon inspection of the internal condition of the instrument, it 
was found that oil was present in the intake line.  It is unknown how this oil could 
have arrived in this position.  The instrument was thoroughly cleaned and back-flushed, and 
returned to service during the maintenance visit.

For the second time period: The degradation of began July 8th.  Data collected during this 
time period are either incorrect or missing and should not be used.
Measurements:sgpaosC1.a0:
  • Particle concentration from Condensation Particle Counter(CPCPartConc)

SGP/AOS/C1 - Optical Particle Counter (PCASP-X) down
DataStreams:sgpaosC1.a0, sgpaosauxC1.a0
Description:
The AOS Optical Particle Spectrometer (PCASP-X sizing probe) was down during these 
periods.  This lowers the laser reference voltage and results in inaccurate sizing.
