The use of the CMIP5 aggregated datasets is unrestricted with the the CMIP5 terms of use.
CMIP6 aggregated datasets build on CMIP6 data and are licensed under Creative Commons CC BY-SA 4.0, following the CMIP6 Terms of Use. Note that some models publish the data under a non-commercial license (CC BY-NC-SA 4.0), although this is discouraged by CMIP.

We acknowledge the World Climate Research Program's Working Group on
Coupled Modelling, which is responsible for CMIP, and we thank the
climate modeling groups (listed in the Atlas inventory folders in this
repository) for producing and making available their model output.
