Global Emissions and Abundances of Chemically and Radiatively Important Trace Gases from the AGAGE Network

Résumé fourni par la source

Global Emissions and Abundances of Chemically and Radiatively Important Gases from the AGAGE Network This data set provides annually updated estimates of global emissions and mole fraction trends for 42 compounds measured by the AGAGE network, including chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, nitrogen trifluoride, methane, nitrous oxide, and selected other compounds. A full description of the data set is available in: Western, L. M., Rigby, M., Mühle, J., Krummel, P. B., Lunder, C. R., O'Doherty, S., Reimann, S., Vollmer, M. K., Young, D., Adam, B., Fraser, P. J., Ganesan, A. L., Harth, C. M., Hermansen, O., Kim, J., Langenfelds, R. L., Loh, Z. M., Mitrevski, B., Pitt, J. R., Salameh, P. K., Schmidt, R., Stanley, K., Stavert, A. R., Wang, H.-J., Weiss, R. F., and Prinn, R. G.: Global emissions and abundances of chemically and radiatively important trace gases from the AGAGE network, Earth Syst. Sci. Data, 17, 6557–6582, https://doi.org/10.5194/essd-17-6557-2025, 2025. 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` and can be downloaded here.
