Climate DT IFS-NEMO SSP3-7.0, daily data on ocean and sea-ice
This dataset contains a selection of ocean and sea-ice fields derived from the DestinE Climate Change Adaptation Digital Twin according to the output of the IFS-NEMO model coupled with the Shared Socioeconomic Pathway 3-7.0 (experiment: SSP3-7.0) as defined in the Scenario Model Intercomparison Project (activity: ScenarioMIP). Fields are regridded from the original HEALPix grid to a regular latitude-longitude grid and distributed with 0.044° spatial resolution and daily temporal resolution. The chunking is optimised for time based and regional analysis.
Access to restricted datasets is available according to the DestinE Access policy
How to download the data
The default (and preferred) way to access the data requires accessing the api.earthdatahub.destine.eu domain and a valid API key.
Method 1: quick access
It is possible to include the token directly in the URL.
1import xarray as xr 2 3xr.open_dataset( 4 "https://edh:<your personal access token>@api.earthdatahub.destine.eu/d1-climate-dt/ScenarioMIP-SSP3-7.0-IFS-NEMO-0001-high-o2d-v0.zarr", 5 chunks={}, 6 engine="zarr", 7)
Method 2: advanced access
The Python snippet gather the token from a netrc file.
