## Welcome to Destination Earth on Hugging Face!

[Destination Earth (DestinE)](https://destine.ecmwf.int) is a flagship initiative of the European Commission to develop a highly accurate digital model of the Earth. It is implemented by [ECMWF](https://www.ecmwf.int), [ESA](https://www.esa.int) and [EUMETSAT](https://www.eumetsat.int).

This organisation hosts the artificial intelligence (AI) and machine learning (ML) work led by ECMWF and its partners within DestinE. AI and ML play an increasingly central role in DestinE: ML-driven models and AI-based software boost the ability to quantify uncertainty in digital twin simulations and make the DestinE system more interactive, using the supercomputing infrastructure of the [EuroHPC Joint Undertaking](https://eurohpc-ju.europa.eu).

This work builds on ECMWF's own ML efforts with its Member States, in particular:

- [Anemoi](https://anemoi.readthedocs.io), the open-source ML framework now powering several state-of-the-art data-driven forecasting models in Europe.
- The [Artificial Intelligence Forecasting System (AIFS)](https://huggingface.co/ecmwf), ECMWF's operational AI-based weather forecasting system.
- [AIFL (AI for Flood Forecasting)](https://huggingface.co/ecmwf), ECMWF's global deep learning model for daily streamflow at catchment scale, including in ungauged basins.

## Objectives

In Phase II of DestinE, AI activities focus on:

- Developing ML-based Earth system model components, working towards a European ML-based Earth system model.
- Enhancing the [Digital Twin Engine](https://destine.ecmwf.int/digital-twin-engine/) to support training and running ML models on EuroHPC systems.
- Applying AI to support uncertainty quantification of digital twin simulations.
- Using AI to make the system more interactive and digital twin data easier to use.

## ML Earth system components

ECMWF is developing [ML-based Earth system components](https://destine.ecmwf.int/ml-earth-system-components/) that will be coupled with the AIFS to form a fully AI-driven Earth system model:

| Component | Description |
| --- | --- |
| [Land](https://destine.ecmwf.int/news/destine-blog-towards-an-ml-based-earth-system-model-land/) | **aiLand**, a global deep learning emulator of land surface processes, trained on ECMWF's physical land model. |
| [Waves](https://destine.ecmwf.int/news/destine-blog-towards-an-ml-based-earth-system-model-waves/) | An AI wave model trained on over 40 years of ECMWF physical wave model output, driven by the AIFS. |
| [Hydrology](https://destine.ecmwf.int/news/destine-blog-towards-an-ml-based-earth-system-model-hydrology/) | Builds on ECMWF's [AIFL](https://huggingface.co/ecmwf) model, developed as part of ECMWF's wider ML activities. |
| [Sea ice](https://destine.ecmwf.int/news/destine-blog-towards-an-ml-based-earth-system-model-sea-ice/) | Learns sea ice and surface ocean evolution from decades of reanalysis data, capturing seasonal cycles and ice-edge behaviour. |
| [Ocean](https://destine.ecmwf.int/news/destine-blog-towards-an-ml-based-earth-system-model-oceans/) | Models the full-depth ocean: temperature, salinity, currents and sea surface height anomaly. |
