+
+## 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.
+
+## 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/) | **AIFL** (AI for Flood Forecasting), estimating daily streamflow at catchment scale, including ungauged basins. |
+| [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. |
