ENA/AOS/C1 - AOS Instrument Repair, Calibration and Modification: Mentor Site Visit
DataStreams:enaaosmetC1.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/AOSMET/C1 - Instrument
DataStreams:enaaosmetC1.a1
Description:
Instrument experienced periodic dropouts.  These were apparent on all channels.  The RH 
sensor went off scale.  During these periods there are no valid points for Air Temperature, 
RH or BP. RH should be considered uncalibrated until this date.  Changing the sensor at 
the end of this period fixed the problem.

  • Rain Duration(rain_duration)
  • Ambient air relative humidity(RH_Ambient)
  • Rain intensity(rain_intensity)
  • Wind speed(WindSpeed)

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.
