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/TRACEGAS/C1 - Reduced calibration from lost instrument control
DataStreams:enaaoscoC1.a1
Description:
Instrument control of calibration Mass Flow Controllers ceased. Unclear why. Lack of 
calibration does not significantly compromise performance.
Measurements:enaaoscoC1.a1:
  • Carbon monoxide (CO) mixing ratio corrected for water vapor concentration and
    calculated with nominal sensitivity correction(co_dry)
  • Nitrous oxide (N2O) mixing ratio corrected for water vapor concentration and
    calculated with nominal sensitivity correction(n2o_dry)
  • N2O mole fraction of during batch measurement(n2o)
  • Calculated CO concentration(co)

ENA/AOSMET/C1 - Reprocessed and Corrected: Wind direction off by 80 degrees
DataStreams:enaaosmetC1.a1
Description:
DATA REPROCESSED and CORRECTED: 
An offset was loaded in the configuration settings of the wind sensor, so the wind 
direction was off by +80 degrees. The raw data were modified and were run through the ingest to 
correct the addressed issue. 

The reprocessed data were Archived in July 2016. Please retrieve the reprocessed data for 
use in your analysis.

You may find these data using the ARM Discovery tool at the following link:

ORIGINAL DQR CATEGORY: Red( Incorrect)

REPROCESSED and CORRECTED DATA ARCHIVED:2016-07

REPROCESS IDENTIFICATION NUMBER: RID 1425

---------------------------------------------------
--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------

An unintentional offset was loaded in the configuration settings of the wind sensor. Wind 
direction during this time is off by +80 degrees

ENA/C1 - Reprocess: Slightly incorrect location fields
DataStreams:enaaosimpactorC1.a1, enaaosimpactorC1.b1
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:
  • East longitude(lon)
  • North latitude(lat)
  • Altitude above mean sea level(alt)

enaaosimpactorC1.b1:
  • Altitude above mean sea level(alt)
  • East longitude(lon)
  • North latitude(lat)
