Subject: ENA/GHG/C1 - Reprocess: addition of height global attribute
Affected 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.

Subject: ENA/GHG/C1 - Reprocessed and Corrected: Valve position fields incorrect type
Affected 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: http://www.archive.arm.gov/discovery/#v/results/s/finst::ghg/fsite::ena/ffac::ena.C1 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.
Measurements
  • mp_valve_position (Value indicates state of the rotary valco valve (range 1 to 8))
