ENA/IMPACTOR/C1 - Impactor not installed
DataStreams:enaaosimpactorC1.a1
Description:
Impactor was not installed and inlet passed all sizes.  This is equivalent to the impactor 
on the 10 um setting.
Measurements:enaaosimpactorC1.a1:
  • Impactor particle size cut(impactor_state)

ENA/NEPHELOMETER/C1 - Impactor not switching
DataStreams:enaaosimpactorC1.a1
Description:
AOS tech was working in the AOS and accidentally unplugged the impactor power supply. This 
left the impactor in the 10 micron state.
Measurements:enaaosimpactorC1.a1:

ENA/AOS/C1 - AOS Instrument Repair, Calibration and Modification: Mentor Site Visit
DataStreams:enaaosimpactorC1.a1
Description:
There was visit of 7 AOS instrument mentors to the ENA AOS during this period of 
instrument repair, calibration and modification. Instruments were occasionally off, or with no 
sample flow, or receiving calibration samples, etc. There was no productive sampling of 
ambient air during this period other than for testing. No data should be used for this period 
as ambient samples.

Note: Two datastream are missing. The CAPS Extinction Monitor and the Greenhouse gas 
instrument.

ENA/AOS/C1 - Reprocess: reprocessing from raw data in preparation for not-yet-released b1 
level
DataStreams:enaaosimpactorC1.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 proccessing software.
Measurements:enaaosimpactorC1.a1:
  • East longitude(lon)
  • North latitude(lat)
  • Impactor particle size cut(impactor_state)
  • base_time
  • time_offset
  • time
  • Altitude above mean sea level(alt)

ENA/AOS/C1 - Impactor stuck at 10 micron
DataStreams:enaaosimpactorC1.a1
Description:
No impactor state data saved for the entire period. Impactor was stuck at the 10 um 
position.
Measurements:enaaosimpactorC1.a1:

DataStreams:enaaosimpactorC1.a1
Description:
Impactor installed and plumbed, HOWEVER, the impactor's 'size read' switch NOT connected.
Measurements:enaaosimpactorC1.a1:

ENA/C1 - Reprocess: Slightly incorrect location fields
DataStreams:enaaosimpactorC1.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:enaaosimpactorC1.a1:

Description:
Instrument mentors working at the site. Sample lines and electrical connections being 
reconfigured. Instruments that had no work done on them may still be affected.
