The DestinE Digital Twin for Climate Change Adaptation (Climate DT) supports adaptation activities by providing innovative climate information on multi-decadal timescales, globally, at scales at which many impacts of climate change are observed. It combines cutting-edge global Earth-system models, impact-sector applications and observations into a unified framework to provide global climate projections and impact-sector information on multi-decadal timescales (1990 to ~2050), at very high spatial resolutions (5 to 10 km).

to contain all available observations from balloons ascents through the atmosphere.
The main geophysical variables are temperature, humidity, and wind speed and wind direction,
as functions of atmospheric pressure levels. The observation platforms include pilot balloons, radiosondes, and ozonesondes.
The main observation data sources are:
- the NOAA Integrated Global Radiosonde Archive (IGRA version 2),
- the NCAR Upper-Air Database (UADB), and

Coupled subsesaonal reforecasts (ENS-C) consisting of 10 perturbed members, each integrated for 46-days, starting on the first of each month between 2006 and 2023 for a total of 216 start dates. The atmospheric model is configured to use the cubic octahedral reduced Gaussian grid with 137 vertical levels and a horizontal resolution of Tco319. The atmosphere is coupled hourly to an eddy-permitting NEMO4-SI3 configuration, which uses 75 vertical levels in the ocean and the eORCA025 grid.
