Subject:	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

Subject:	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.
Measurements:	awraoscpcfM1.a1: Aerosol concentration averaged over times to match N_CCN(concentration) awraoscpcfM1.b1: Aerosol concentration averaged over times to match N_CCN(concentration)

Subject:	AWR/CPC/NEPHELOMETER/PSAP/M1 - Low impactor flow
DataStreams:	awraoscpcfM1.b1, awraoscpcfM1.a1
Description:	CPC inlet not properly connected to the sample lines. Flow through the impactor below nominal. Instruments sampling cabin air at least part of the time.

Subject:	AWR/CCN/CPC/M1 - Concentration difference
DataStreams:	awraoscpcfM1.a1, awraoscpcfM1.b1
Description:	Various tests performed to understand why the CCN counts sometimes exceed those of a co-located CPC. Instrument functioning normally, but occasionally sampling cabin air during this period or running with internal flow lines opened for flow measurements.

Subject:	AWR/CPC/M1 - Communication problem
DataStreams:	awraoscpcfM1.a1, awraoscpcfM1.b1
Description:	The configuration file used for LabVIEW to communicate with the instrument was changed causing a communication problem. The file was replaced and the instrument is now functioning properly.

Subject:	AWR/CPC/M1 - Communication error
DataStreams:	awraoscpcfM1.a1, awraoscpcfM1.b1
Description:	A configuration file used to run the LabVIEW VI for the cpcf data collection was modified causing a communication error. This error was corrected, but some data was missing as a result.
