Subject:
AWR/CCN/CPC/M1 - Concentration difference
DataStreams:awraosccn1colM1.b1, awraoscpcfM1.a1, awraosccn100M1.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.
Suggestions: 
Use data with caution
