Obtaining observational data

Obtaining observational data

Unfortunately, it is not possible to automate staging of the observational data used in this calculation. Here we provide instructions, however, for manually accessing these data products, which are all publicly available, but in several instances, require registration to access.

_config_calc.yml defines a variable project_tmpdir_obs, which specifies the directory in which to store the data referenced here.

Aircraft observations (complete merge products)

For each campaign, download the following files into ${project_tmpdir_obs}/aircraft-merge-products subdirectory.

HIPPO

ORCAS

ATom

  • ATom merge products (Version 2.0):

  • MER10_DC8_ATom-1.nc, MER10_DC8_ATom-2.nc, MER10_DC8_ATom-3.nc, MER10_DC8_ATom-4.nc

  • MER-MED_DC8_ATom-1.nc, MER-MED_DC8_ATom-2.nc, MER-MED_DC8_ATom-3.nc, MER-MED_DC8_ATom-4.nc

  • MER-PFP_DC8_ATom-2.nc, MER-PFP_DC8_ATom-3.nc, and MER-PFP_DC8_ATom-4.nc

  • from https://doi.org/10.3334/ORNLDAAC/1925

ObsPack data files

Download netcdf ObsPack files from: https://gml.noaa.gov/ccgg/obspack for ObsPack versions:

  • obspack_co2_1_GLOBALVIEWplus_v4.2.2_2019-06-05 (only the hip, orc, and tom aircraft files are needed)

  • obspack_co2_1_GLOBALVIEWplus_v5.0_2019-08-12 (only the hip, orc, and tom aircraft files are needed)

  • obspack_co2_1_GLOBALVIEWplus_v6.0_2020-09-11 (only the Southern Ocean records listed in Table S1 and the hip, orc, and tom aircraft files are needed)

  • obspack_co2_1_ATom_v4.0_2020-04-06

  • obspack_co2_1_CARBONTRACKER_CT2017_2018-05-02 (only the hip, orc, and tom aircraft files are needed)

  • obspack_co2_1_GLOBALVIEWplus_v7.0_2021-08-18 (only the LSCE AMS record and the NOAA in situ Gould record needed)

Expand the gzipped tar files into ${project_tmpdir_obs} for each obspack; preserve the ${obspack}/data/nc subdirectories.

WDCGG

Download the following files into a ${project_tmpdir_obs}/WDCGG subdirectory:

Expanding the gzipped tar files and preserve the /data/nc/* subdirectories.

SIO O2

Download into ${project_tmpdir_obs}/sio subdirectory, csv files for CGO, PSA, and SPO from https://scrippso2.ucsd.edu/cosub2sub-data.html

NCAR in situ Gould record

Download into ${project_tmpdir_obs}/ncar-lmg subdirectory gzipped text file https://archive.eol.ucar.edu/homes/stephens/GO2/lmg_all_results.txt.gz and unzip

NIWA

Download into ${project_tmpdir_obs}/niwa subdirectory text file https://niwa.co.nz/static/tropac/co2/bhd/archive/co2_bhd_surface-insitu_57_1978-2019_hourly.txt

Minimal file listing when finished (extra files can be kept if space allows):

Once your done, ${project_tmpdir_obs} should include at least these files in this structure:
