CarbonTracker-CH4 includes access to the following model and observational data. Please see Citation for the CarbonTracker usage policy.

Users may find the NASA/GISS Panoply NetCDF Viewer helpful for working with CarbonTracker NetCDF files.

  • 3-D Mole Fractions

    CH4 mole fraction fields are available in netCDF format. Time resolution is 3-hourly. Mole fractions are available on the global 3x2-degree grid. 3-D visualization of the contents of these files is included on the website under the CH4 Visualization tab.

  • Fluxes

    Global monthly surface fluxes at 3x2-degree spatial resolution in netCDF format. Provided as flux components: microbial, fossil, and pyrogenic emissions. Images of the contents of these files are included on the website under the Fluxes tab.

  • Preprocessed Observations

    Observations of atmospheric CH4 and δ13C-CH4 preprocessed for use in the CarbonTracker-CH4 assimilation system are available in ObsPack NetCDF format. The time series and information of each observation are included on the website under the Observations and Evaluation tabs.
