The CMIP6 GCM runs were developed in support of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR6). This dataset includes downscaled projections from ScenarioMIP model runs for which daily scenarios were produced and distributed through the Earth System Grid Federation. This collection contains 34 different models. One model, "GFDL-CM4," has data for two different configurations that can be differentiated by further filtering on the *grid_label* property. Bands are replaced as new versions become available and the *version* property is updated with them. See also [the provider tech note](https://www.nccs.nasa.gov/wp-content/uploads/2024/03/NEX-GDDP-CMIP6-Tech_Note_4.pdf).

It is one of: - ACCESS-CM2 - ACCESS-ESM1-5 - BCC-CSM2-MR - CESM2 - CESM2-WACCM - CMCC-CM2-SR5 - CMCC-ESM2 - CNRM-CM6-1 - CNRM-ESM2-1 - CanESM5 - EC-Earth3 - EC-Earth3-Veg-LR - FGOALS-g3 - GFDL-CM4 (see *grid_label* for additional information) - GFDL-ESM4 - GISS-E2-1-G - HadGEM3-GC31-LL - HadGEM3-GC31-MM - IITM-ESM - INM-CM4-8 - INM-CM5-0 - IPSL-CM6A-LR - KACE-1-0-G - KIOST-ESM - MIROC-ES2L - MIROC6 - MPI-ESM1-2-HR - MPI-ESM1-2-LR - MRI-ESM2-0 - NESM3 - NorESM2-LM - NorESM2-MM - TaiESM1 - UKESM1-0-LL | | scenario | STRING | Name of the CMIP6 scenario. It is one of: - historical (retrospective model runs pre-2015) - ssp245 - ssp585 | | year | DOUBLE | Calendar year | | month | DOUBLE | Calendar month | | day | DOUBLE | Calendar day | | grid_label | STRING | The grid label, which is only set when differentiating simulation results for the 'GFDL-CM4' model. It is one of: - gr1 - gr2 | | license | STRING | The license under which a model is released. It will be one of: - CC-BY-4.0 (Creative Commons Attribution 4.0 International) - CC0-1.0 (Creative Commons Zero v1.0 Universal) | | interpolated | STRING | Present and 'true' if data for a particular day has been filled in using the value from the previous day. This happens when the simulation does not produce a data band for every day in the year. The following models always duplicate the last day in leap years because they only yield 365 bands: 'BCC-CSM2-MR', 'CanESM5', 'CESM2', 'CESM2-WACCM', 'CMCC-CM2-SR5', 'CMCC-ESM2', 'FGOALS-g3', 'GFDL-CM4', 'GFDL-ESM4', 'GISS-E2-1-G', 'INM-CM4-8', 'INM-CM5-0', 'KIOST-ESM', 'NorESM2-LM', 'NorESM2-MM', 'TaiESM1'. These models yield 360 bands per year and have the outstanding 5 or 6 days filled by duplicating one every 60-70 days: 'HadGEM3-GC31-LL', 'HadGEM3-GC31-MM', 'KACE-1-0-G', 'UKESM1-0-LL'. 'IITM-ESM' only has 364 bands in years divisible by 5 (and does not have data for 2100 at all), so the final day is always duplicated, plus the midpoint day in leap years. | | version | DOUBLE | The version of the asset, possible values are 1.0, 1.1 and 1.2 | ### Terms of Use **Terms of Use** As of September 2022, all NEX-GDDP-CMIP6 outputs are made available by the provider under a blanket [CC0-1.0](https://spdx.org/licenses/CC0-1.0.html) license. Some models in the original dataset were initially released under 'CC-BY-SA-4.0' (Creative Commons Attribution Share Alike 4.0 International), as required by the data license of the original CMIP6 inputs, and individual EE Images may still carry a "license" property inherited from that original CMIP6 file metadata. The blanket CC0 license supersedes those properties. ### Citations Citations: - Thrasher, B., Maurer, E. P., McKellar, C., \& Duffy, P.
