Subject: OLI/GHG/M1 - Reprocessed and Corrected: addition of height global attribute
Affected Datastreams: oliaosghgM1.a1
Description DATA REPROCESSED and CORRECTED: The mentor has requested the addition of a 'height' global attribute to record the inlet height. The OLI instrument was recently relocated inside the AOS container (on or about August 12, 2016). So, prior to that date, the height was 6.2179 meters and after that date the height became 10 meters. There will also be some minor changes in the oliaosghgauxM1.a1 data. NaN values have been replaced by values of -9999. The data were archived in May 2017. Please retrieve the reprocessed data for use in your analysis. ORIGINAL DQR CATEGORY: Transparent (Does not affect quality) REPROCESSED and CORRECTED DATA ARCHIVED:2017-05 REPROCESS IDENTIFICATION NUMBER: RID 1508 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- The mentor has requested the addition of a 'height' global attribute to record the inlet height. The OLI instrument was recently relocated inside the AOS container (on or about August 12, 2016). So, prior to that date, the height was 6.2179 meters and after that date the height became 10 meters. 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.
