ENA/GHG/C1 - System probationary period
DataStreams:enaaosghgC1.a1
Description:
System probationary period, may not be useful for science data due to non-optimal 
functioning of the measurement system.

Subject:
ENA/GHG/C1 - Reprocessed and Corrected: Valve position fields incorrect type
DataStreams:enaaosghgC1.a1
Description:
DATA REPROCESSED and CORRECTED: 

The raw data variable mp_valve_position was being read as an integer instead of a float. 
The aos_ingest logic was corrected and the data were run through the corrected ingest to 
fix the issue.

The data were reprocessed 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 1453

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

Raw data variable MP_VALVE_POSITION needs to be read as a float and not integer.

Subject:
ENA/GHG/C1 - Reprocess: addition of height global attribute
DataStreams:enaaosghgC1.a1
Description:
The mentor has requested the addition of a 'height' global attribute to record the inlet 
height. The inlet for the ENA AOSGHG has always been at a height of 10 meters, but the 
datastreams did not have this new global attribute. 

Both the aosghg.a1 and aosghgaux.a1 datastreams will be updated to add this new global 
attribute. 

The mentor has requested that the entire dataset be reprocessed to make this addition to 
the global attributes. We will be releasing dowstream aosghg.b0 and aosghg.b1 processing 
that will incorporate this new global attribute from the a1 input datastreams.

  • Carbon dioxide dry volume mixing ratio(co2_dry)
