  • Simulated CO2 tracer concentrations in the Northern Hemisphere from a tagged transport model GEOS-Chem v12.0.0

    work
    Creator:
    Lin, Xin, Keppel-Aleks, Gretchen, Rogers, Brendan M., and Birch, Leah
    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.
