Biogeochemical Argo Adjusted Oxygen Data

This archive contains two netCDF files used in the work reported by Johnson and Bif (2021). These files contain vertical profiles of corrected dissolved oxygen (Argo variable DOXY_ADJ), temperature, salinity, pressure, location, and time data obtained by profiling floats in the Biogeochemical-Argo array. The files were created by downloading all Argo .Sprof files directly from the Argo Global Data Assembly Center (ftp://usgodae.org/pub/outgoing/argo or ftp://ftp.ifremer.fr/ifremer/argo) in December 2020. The corresponding monthly snapshot (December 2020, https://doi.org/10.17882/42182#79118) of the Argo database will contain these .Sprof files, in addition to data for floats that do not have biogeochemical sensors. Merged netCDF (.nc) data files were then created by importing all of the .Sprof files into Ocean Data View (ODV, odv.awi.de) using the List File Generator tool in ODV. After eliminating 9 floats with anomalous adjusted oxygen data, which are listed in Johnson and Bif, the vertical profiles for all floats with adjusted oxygen data were exported as two netCDF files using ODV. One file contains data in the northern hemisphere (90N to 10S), which the second contains data from 0N to 90S). The files overlap from 0 to 10S, which enabled all equatorial data (10N to 10S) to be processed with one file. The netCDF files contain the adjusted dissolved oxygen concentration in µmol/kg (DOXY_ADJ), oxygen anomaly (oxygen minus oxygen saturation at one atmosphere pressure), temperature, salinity, pressure (dbar), profile position and date, quality flags for each observation, and float WMO number and type.
