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.
Measurements:enaaoscpcfC1.a1:
  • Concentration(concentration)

Subject:
ENA/CPC/C1 - Instrument Not Sampling due to repair and calibration
DataStreams:enaaoscpcfC1.a1
Description:
During this period the CPC was shipped back to the manufacturer to mitigate damage due to 
flooding. The instrument was found to be flooded. Repair and calibration was performed. 
Most of the down time was related to delays in shipment due to customs on Terceira Island.

Subject:
ENA/CPC/C1 - Data reprocessed to account for vacuum port too low
DataStreams:enaaoscpcfC1.a1
Description:
Recorded calibrations relating the effect on flow of reduced nozzle and orifice pressure 
was used to correct the data.

When the CPC was put back in operation, the external vacuum port was connected to a vacuum 
line, which didn't provide enough pull.
Measurements:enaaoscpcfC1.a1:
  • Concentration(concentration)

ENA/CPC/C1 - Reprocess: reprocessing from raw data in preparation for not-yet-released b1 
level
DataStreams:enaaoscpcfC1.a1
Description:
End to end reprocessing to generate new a1 datastreams is needed so that when the 
harmonization software is released to production, we will be ready with the a1 datastreams that 
are input to the subsequent processing software.

Subject:
ENA/C1 - Reprocess: Slightly incorrect location fields
DataStreams:enaaoscpcfC1.a1
Description:
Some of the instruments are being processed with the previous "GRW-Azores" lat/lon/alt 
instead of the new "ENA-Azores" lat/lon/alt. The differences are minor, but will be 
corrected. The respective GRW and ENA lat, lon, and alt values are as follows:
 
GRW  lat = 39.0911 ;
ENA lat = 39.0916 ;
GRW  lon = -28.0297 ;
ENA  lon = -28.0257 ;
GRW  alt = 26 ;
ENA  alt = 30.48 ;
Measurements:enaaoscpcfC1.a1:
  • East longitude(lon)
  • Altitude above mean sea level(alt)
  • North latitude(lat)
