Methodology
  • The data are model output from a tagged CO2 tracer transport model conducted with the GEOS-Chem version 12.0.0 ( http://www.geos-chem.org, doi: 10.5281/zenodo.1343547). Thirteen land flux regions were defined and tagged in the model to separate their imprints on the long-term atmospheric CO2 seasonal amplification in the Northern Hemisphere.

  • The model was run at a resolution of 2.0° in latitude by 2.5° in longitude with 47 vertical levels, prescribed with land carbon fluxes from the CO2 inversion CAMSv17r1 (available at  https://apps.ecmwf.int/datasets/data/cams-ghg-inversions/) as boundary conditions. The model was driven by hourly meteorological fields from MERRA2 reanalysis ( https://gmao.gsfc.nasa.gov/reanalysis/MERRA-2/; available at  http://geoschemdata.computecanada.ca/ExtData/GEOS_2x2.5/MERRA2/) at a timestep of ten minutes.

  • The data contain the daily averaged concentrations of these CO2 tracers simulated by the model between 1980-01-01 and 2017-12-31, and sampled at the surface level and two mid-tropospheric levels (700 millibar and 500 millibar). The full model output is available on request to Xin Lin ( [email protected]) and Gretchen Keppel-Aleks ( [email protected]).
Description
  • The data contain the daily-averaged atmospheric concentrations of CO2 tracers in the Northern Hemisphere simulated from a tagged tracer transport model GEOS-Chem v12.0.0. Thirteen land flux regions are defined and tagged in the model to separate their imprints on the long-term atmospheric CO2 seasonal amplification in Northern Hemisphere. A file describing the delineation of these land flux regions is also provided. See the README file for more details on the dataset and model configurations.
