ENA/CPC/C1 - Reprocess: reprocessing from raw data in preparation for not-yet-released b1 
level

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.

ENA/ACSM/C1 - Instrument waiting for spare parts

The ACSM was out of service while waiting for a replacement valve and a replacement turbo 
molecular vacuum pump. The data acquisition was stopped and the instrument put in standby 
mode.

ENA/OZONE/C1 - Reprocess: Under reporting ozone concentration

Switching valve developed an internal leak that gradually worsened. Reported instrument 
values are under-representations of the ambient ozone concentration during this period. The 
under reporting worsens from 85% to 77% over the course of this DQR. No corrections have 
been applied at this point.

• Ozone concentration(ozone)

ENA/HTDMA/C1 - Incorrect RH and air flow

The HT-DMA internal RH sensor was sending out data in a format that was not correctly 
interpreted by the instrument software. This led the software to assume an incorrect RH 
reading and set the humid and dry air flows at incorrect values, affecting RH and other 
internal flows.

ENA/MAO/OLI/PGH/PVC/SGP/TWP/DLPROF/C1/C3/M1 - Reprocess: Suspect error estimates

The current dlprofwind4news VAP generates time- and height-resolved estimates of wind 
speed, wind direction, and corresponding uncertainties from Doppler lidar PPI scans. A recent 
comparison with a heavily instrumented tall tower (BAO) has shown that the error 
estimates are biased low and exhibit poor correlation with the observed lidar-tower differences. 
We note that the measurements themselves (i.e. wind speed and direction) are minimally 
affected by this issue.

ENA/DL/DLPROF/C1 - Reprocess: Azimuth calibration off

The azimuth calibration is off by ~2deg. This happened after the system was reinstalled 
following the recent hurricane. All scanning data and wind VAP data will be reprocessed.

ENA/ACSM/C1 - Reinstallation evaluation period

After reinstallation of the ACSM (see outage period covered in black DQR D151030.1), the 
instrument mentor evaluated the performance of the instrument for several days. During 
this time, data are suspect.

ENA/C1 - Reprocess: Slightly incorrect location fields

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 ;

ENA/DL/DLPROF/C1 - Reprocess: Incorrect serial number

The instrument serial number that appears in the netcdf files global attributes is 
incorrect. The correct serial number is 0514-84.

• base_time

ENA/AOS/C1 - incorrect data

During a measurement of the inlet flow rate, the cpcf inlet became plugged and the 
instrument was flooded with butanol.  After removing the butanol and allowing the system to dry, 
the cpc returned to normal operation.

ENA/OZONE/C1 - Air inlet plugged

The zero air inlet was plugged after a leak test.  Mentor failed to identify the problem 
until 2016-07-05.  Data should be valid.

• Ozone pressure(ozone_pressure)

ENA/OZONE/C1 - Failing pump

The pump was failing, and the operator attempted a repair.  Eventually, the flow bypassed 
the pump internally and was replaced with an external HTDMA vacuum pump.  Data appear 
valid since the flow only affects the internal calibration source and not the ambient 
measurement.

ENA/OZONE/C1 - Water condensing in the line

Instrument suffered major oscillations in the signal.  Working with Operator it was 
discovered that the Split System Air Conditioner was blowing directly on the Ozone detector.  
Water was condensing in the line.  The air was redirected and the temperature setpoint 
raised.  This reduced but didn't entirely eliminate the oscillations.
