At a minimum of 2 months prior to publication or presentation of works that include FRM4GHG data, please, contact the authors and provide a description of the intended publication or presentation. If any of the FRM4GHG partners makes a significant intellectual contribution to the research, or if FRM4GHG data is essential to the work, co-authorship of the FRM4GHG consortium would normally be expected. This should be discussed at an early stage in the work. If none of the FRM4GHG partners responds after 3 emails distributed over a 2-months period, the data are licensed under a cc-by 4.0 license.
