SGP/AOS/S01 - Instrument Sampling From Cabin and Not From Aerosol Inlet

When examining the ratio of the total number concentration from the SMPS vs. the CPCF, a 
shift in the ratio was detected following a site visit where the SMPS was used to 
calibrate other instruments.  Upon further examination by site ops, it was noticed that the 
tubing from the aerosol inlet to the SMPS was not connected.  The instrument had been sampling 
from the cabin and not from the atmosphere.

Users may use this data with caution, but may wish to exclude it from analysis.  The 

shape of the aerosol size distribution is qualitatively similar to periods immediately 
preceding and immediately following this event.  The SMPS total concentration is lower 
than the concentration reported by the cpcf during this period.
