The instrument mentor has been looking at marine CCN results for many years now, and is 
not really convinced there is a problem. CCN counts get very low in marine environments, 
down to 5 to 10 counts. Many times this is sudden with a change in the wind.

ENA/CCN/C1 - Problem with time fields
DataStreams:enaaosccn100C1.a1
Description:
During the ENA deployment the CCN instrument clock was not synched with a time server 
until 12/2/2014.  Starting at about 11/03/2013 the CCN was 60 seconds slow.  From that time 
until the time was manually corrected on 10/07/2014 at 16:00:00 the CCN time gradually got 
faster relative to the CPC until it was approximately 10 minutes fast. On 12/2/2014 at 
20:28:30 the CCN was configured to automatically correct its time from the Unit 1 CPU.  
Since that time the CCN has been within 2 seconds of the time server except at startup.  
More recently the setting was changed to keep the CCN within about .6 sec.  Generally the 
time is being corrected by time client about once every 3 days.  

There have been 2 startups since the time synching was configured.  At these times the 
time was off by more, but was immediately corrected.  On 12/30/2014 at 19:28:01 the time was 
fast 66.235 sec. at startup.  On 01/16/2015 the time was fast 38.512 sec. at startup.

The  Document  shows the times of the peaks used to approximate the 
error in the time. The time was checked about once a week and its assumed that the time 
drifted gradually between the times in the file.

Vacuum was lost very briefly to the instrument for an unknown reason.  The instrument then 
showed evidence of flooding by an increase in the frequency of the butanol fill cycles, 
increase in nozzle pressure, and decrease in orifice pressure.

ENA/CPC/C1 - Instrument problem
DataStreams:enaaoscpcfC1.a1
Description:
It was found that the wrong vacuum source was connected to the vacuum port on the CPC and 
didn't provide enough pull for the instrument to run correctly.  While the problem was 
being rectified, there was a period where the CPC was sampling from the instrument cabin 
and not from the ambient.  Therefore data during this time is not representative of the 
ambient concentration of aerosol in the atmosphere and should not be used as such.
