CR-CMIP-0-4-0	modify	comment_post_publication	CR-CMIP-1-0-0 switches to much more conventional naming for gases. The affected gases are: c2f6 (previously pfc116), c3f8 (pfc218), c4f10 (pfc3110), c5f12 (pfc4112), c6f14 (pfc5114), c7f16 (pfc6116), c8f18 (pfc7118), cc4f8 (pfc318) and ch3ccl3 (hcc140a).\nA DOI is now also included in each file. Please use it so we can track usage of these files.\nIn terms of science, CR-CMIP-1-0-0 updates to the latest ice core and AGAGE data, as well as using better data sources for HFC23, CF4, C2F6 and C3F8 than CR-CMIP-0-4-0. CR-CMIP-1-0-0 also provides a smoother transition from ice core based records to more recent records (i.e. flask and in-situ samples) and more sensible pre-industrial values for gases with non-zero pre-industrial concentrations. It also uses the Scripps CO2 record to handle the period from 1959 to the start of the flask and in-situ samples from other networks.\nThe CR-CMIP-1-0-0 dataset also provides much better information about the original data sources.\nAs a result, CR-CMIP-0-4-0 is deprecated.\nFor the full CHANGELOG, see [here](https://github.com/climate-resource/CMIP-GHG-Concentration-Generation/blob/main/CHANGELOG.md).\nFor basic analysis of the changes between versions, see [this repo](https://github.com/climate-resource/CMIP6-vs-CMIP7-GHG-Concentrations).
