Subject:
SGP/AOS/C1/ - Pump failure
DataStreams:sgpaosccnC1.a1
Description:
The ratio of CCN to CN started to noticeably decline around 20070901. After a site visit 
on 20071023, the mentor found a problem with the instrument flows and diaphragm pump.  The 
instrument was return to Boulder, CO for repair. The diaphragm pump was repaired and the 
flows re-calibrated. The instrument was returned to service 20071113. 

The CCN data show qualitative changes in the number of droplets formed with changes in 
supersaturation. Because the pump was not working properly and the flows were likely 
incorrect, the numbers are not quantitative.

SGP/AOS/C1 - Suspected leak in CCN
DataStreams:sgpaosccnC1.a1
Description:
The CCN signal started a slow decline during this period. The instrument was removed and 
shipped back to the mentor for repair. A leak was found in the instrument which would've 
decreased the over all signal. Whether this leak affected the rate of CCN growth with %SS 
is uncertain.
