After the embargo period (see the Workflow for contributions to ISIMIP), ISIMIP data is transferred to the ISIMIP repository (or the ESGF server), where it is immediately made publicly available. Every data set is assigned a specific license and documented in the appropriate sector and simulation-round specific DOI (see Notes on DOIs).
In addition, given that ISIMIP data might be derived from other data sets, those rights also have to be considered.
Before assigning a license to a data set of your own creation, please check the licenses of all data sets you used in its creation, as some licenses are inherited (e.g., CC BY-SA 4.0). However, there are nuances to license inheritance, depending on whether parts of the source data used appear identically in your simulation data.
Please clarify the legal consequences of licensing with your own institutions before assigning any license to your simulation data, as the database producer right is often not with the researchers. If you are associated to PIK, this issues are covered in the Open Science Policy of the Institute (https://www.pik-potsdam.de/en/output/software-data-models/open-source/PIKOpenSourceOpenDataPolicyMay2019.pdf).
As of ISIMIP3, we encourage the use of the CC0 - Public Domain Dedication for all model output. Under CC0, all copyright interests and database rights are waived, so we consider this perfectly suitable to use with ISIMIP data. Working under the CC0 waiver allows anyone to use the data for derivative work in any way and for any purpose, including commercial purposes. Regardless of the legal implications, we request to follow our terms of service, including the correct form of attribution of the datasets. For more information, see the CC0 FAQs.
For ISIMIP2 (and Fast Track), ISIMIP's preferred license for output data was the CC BY 4.0, but some modelling groups selected other Creative Commons (CC) licenses. You can find every available model output license information in the tables below (ISIMIP2b, ISIMIP2a, FastTrack) and in our ISIMIP model data base (most up to date).
The modelling groups with individual model restrictions in Fast Track are listed here.
IMPORTANT: Creative Commons (CC) licenses cannot be revoked. Please choose your license carefully.
