title: Data set of global emissions and mole fraction trends of ozone-depleting substances and greenhouse gases using measurements from the Advanced Global Atmospheric Gases Experiment (AGAGE) and a 12-box model

description: Data set of Global emissions and mole fraction trends of ozone-depleting substances and greenhouse gases using measurements from the Advanced Global Atmospheric Gases Experiment (AGAGE) and a 12-box model

This data set provides annually updated estimates of global emissions and mole fraction trends for 42 compounds measured by the AGAGE network, including methane, nitrous oxide, chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, nitrogen trifluoride, and selected other compounds.

A full description of the data set are available in Western et al., 'Global emissions and mole fraction trends of ozone-depleting substances and greenhouse gases using measurements from the Advanced Global Atmospheric Gases Experiment (AGAGE) and a 12-box model', submitted to Earth System Science Data.

Each compound has two directories, `inputs` and `outputs`. The `inputs` contain the semihemispheric mole fractions and a priori emissions used to derive the quantities in the `outputs` folder.

The doi of the measurement data sets used are contained in the files `/inputs/*_obs_agage.csv`.

AGAGE Data Policy

These data are made available to the scientific community and public to improve understanding of climate change and ozone depletion and to lead to new scientific insights. AGAGE relies on the ethics and integrity of the user to ensure that AGAGE scientists receive fair credit for their work.

If the data are obtained for potential use in a publication or presentation, AGAGE station PIs should be informed at the outset of the proposed work. Station PI contact information is located in the station pages. If the AGAGE data are essential to the work, co-authorship on publications may be appropriate. Manuscripts using the AGAGE data should be sent early to the AGAGE contacts for review before they are submitted for publication, so we can ensure that the quality and limitations of the data are accurately represented.

Every effort is made to produce the most accurate and precise measurements possible. However, we reserve the right to make corrections to the data based on recalibration of standard gases or for other reasons deemed scientifically justified. We are not responsible for results and conclusions based on use of these data without regard to this warning.

Reciprocity Agreement

Use of these data implies an agreement to reciprocate. Laboratories making similar measurements agree to make their own data available to the general public and to the scientific community in an equally complete and easily accessible form. Scientists are encouraged to make available to the community, upon request, their own modelling tools used in the interpretation of the AGAGE data, namely well documented model code, transport fields, and additional information necessary for other scientists to repeat the work and to run modified versions.

Acknowledgements

Publications must state: “AGAGE is supported principally by the National Aeronautics and Space Administration (USA) grants to the Massachusetts Institute of Technology and the Scripps Institution of Oceanography."

Additional statements must be included to acknowledge funding for the individual stations. These are located on the individual station pages.
