AWR/CPC/M1 - Failed pump
DataStreams:awraoscpcfM1.a1, awraoscpcfM1.b1
Description:
The pumps that draw air into the instrument for particles to be counted failed.  The 
values reported by the instrument are not representative of the particle number concentration 
in the atmosphere
Measurements:awraoscpcfM1.a1:
  • Concentration(concentration)
awraoscpcfM1.b1:
  • Concentration(concentration)

AWR/CPC/M1 - Instrument Startup, No Data Collected
DataStreams:awraoscpcfM1.a1
Description:
At the instrument startup of the AMF2 deployment, the computers were turned on before the 
instruments were turned on.  The data collection starts automatically on instrument 
startup, but if the instruments are not on and connected, the data text files will contain 
missing data codes such as NaN or -9999.

Subject:
AWR/CPC/M1 - CPC Flooding
DataStreams:awraoscpcfM1.b1, awraoscpcfM1.a1
Description:
Following a routine flow rate check, the CPC showed signs of flooding with the orifice 
pressure dropping below 10 kPa.  The butanol fill bottle was removed from the system.  After 
two days of continuous running the system dried out and the orifice pressures were 
restored to nominal values.  The data from this period is suspect.
