SGP/CCN/C1 - % super saturation values change after instrument calibration
DataStreams:sgpaosccn1colC1.b1
Description:
% super saturation scan values during this time period were 0.12, 0.23, 0.4, 0.85, 0.51, 
0.29 and 0.18. Before and after this time period the % super saturation scan values are 
0.15, 0.25, 0.4, 0.8, 0.5, 0.3 and 0.2.

SGP/AOS/C1 - Wildfire smoke plumes advecting over facility
DataStreams:sgpaosccn1colC1.b1
Description:
Smoke from nearby wildfires advected through SGP C1 during the listed affected time 
ranges, resulting in high signals observable in many of the listed AOS datastreams.
Measurements:sgpaosccn1colC1.b1:
  • AOS number concentration of CCN(N_CCN)
  • AOS CCN droplet count by bin size(N_CCN_dN)

SGP/CCN/C1 - Problem with flow control regulation
DataStreams:sgpaosccn1colC1.b1
Description:
A problem with flow control regulation. The instrument was returned to manufacture DMT for 
repair. The column was found cracked and replaced. Data scans from 5/6/2016 15:36 to 
5/10/2016 16:00 use the default scan mode that steps from 0.2 to 1.0 %ss. After this time, 
the pyramid stepping scheme is implemented.
