Earth Systems Lab 2026

Applied AI for Planetary Stewardship

Earth Systems Lab (ESL) brings together leading researchers in machine learning, Earth science, space exploration, climate science, disaster response, and related disciplines to tackle high-impact global challenges through applied AI.

Hosted in collaboration with the European Space Agency (ESA), ESL combines interdisciplinary research, rapid experimentation, and world-class mentorship in an intensive summer research sprint designed to create meaningful scientific and engineering outcomes.

Welcome to ESL 2026

The ESL Bootcamp is the launchpad for the research sprint, bringing participants together in Frascati, Italy, home to ESA’s Earth Observation Centre.

Over the course of ESL, researchers collaborate in interdisciplinary teams to explore ambitious ideas, develop AI pipelines, and create reproducible research outcomes with real-world applications.

Participants are selected not only for technical excellence, but also for their ability to thrive in collaborative, high-performance research environments.

What is Earth Systems Lab?

Earth Systems Lab is an applied artificial intelligence research cycle focused on advancing machine learning, data science, and high-performance computing for problems of material importance to humanity.

ESL tackles challenges across:

  • Earth science

  • Climate research

  • Disaster response

  • Space exploration

  • Planetary stewardship

  • Energy transition

The ESL’s core approach is pairing machine learning researchers with domain experts in intensive interdisciplinary teams.

While the research sprint itself runs for eight weeks, the full ESL research cycle extends over approximately twelve months, from challenge definition through to technical memos, scientific outputs, and deployable data products.

How ESL Works

Interdisciplinary Research

Each challenge team combines expertise from:

  • Machine learning and AI

  • Earth and climate science

  • Space science

  • Cyber-physical systems

  • Planetary science

  • Astrobiology and related domains

Teams are supported by faculty leads, technical mentors, partner organisations, and expert reviewers.

Rapid Iteration

ESL is structured around accelerated experimentation and continuous review. Teams rapidly prototype ideas, evaluate approaches, refine ML pipelines, and iterate toward reproducible outcomes.

2026 Research Challenges

MoEarths

Can we build on learnings from model switch out and uncertainty awareness to create optimal foundation model performance that can act as a unified estimator of truth? 

There is no operational Earth-scale MoE (Mixture of Experts) system deployed today. The MoEarths (Mixture of Earths) challenge proposes a shift from selecting a single "best" model to a new paradigm of adaptive switch-out, prototyped during FDL 2025 (SHRUG) and FDL 2024 (MAESTRO). The applied aspect of this challenge is to look at an application that requires a transparent and uncertainty-aware Earth state estimator. MoEarths could provide the transparent third-party assessment required for forestry management or next generation carbon reporting and certification, addressing conflicting representations of biomass, land use, and carbon sequestration create a trust gap that complicates regulatory compliance. This project would be the first attempt to make a transparently arbitrated, uncertainty-quantified Earth state estimate.

Living Forests 

Can we build a precursor foundation model of a dynamic, living system using ESA’s Biomass and Sentinel missions? 


This challenge would develop the first AI Forest Foundation Model designed to learn the underlying physics of forests built on Biomass, Sentinel 3 and FLEX data. This effort would explore foundation model approaches that make predictions based on the latent structure in the embedding space. The approach effectively would produce a high-dimensional representation of the global forest, capable of simulating the outcomes of queries, its carbon carrying capacity and assessing resilience. A living forest model would work in concert with planned and existing SAR and optical foundation models in detecting biomass variation across diverse biomes, from boreal to tropical, by maintaining an internal representation of the forest in the latent space, helping to understand how the Earth’s living systems function and how they respond.

Tropical Cyclone Dynamics 

Can we predict tropical storm intensity?  


While recent work has successfully reconstructed 3D cloud structures at a three-kilometer scale, these models remain structural snapshots that lack the integrated thermodynamics and kinematics necessary to anticipate the destructive potential of rapid intensification events. This challenge invites the development of a novel multimodal AI framework that fuses 3D cloud morphology with temperature, precipitation and synthetic aperture radar (SAR) wind speeds. Wind speed fields derived from SAR will be paired with geostationary cloud-top observations and precipitation profiles from polar-orbiting sensors. These sources have different spatial/temporal resolutions and observation frequencies, which make this a bold challenge. Handling irregular grids will require sophisticated data fusion (for instance with graph neural networks or transformers and techniques for geospatial information encoding).

Research Outcomes

ESL outcomes are typically developed to mid-Technology Readiness Level (TRL), meaning:

  • AI and ML pipelines are validated in realistic scenarios

  • Results are reproducible

  • Scientific or engineering findings can be documented in technical memos or publications

  • Workflows follow best practices in software and data engineering

Community-Driven Excellence

A defining feature of ESL is its collaborative culture. Teams are encouraged to combine ambitious thinking with supportive working practices that enable creativity, resilience, and high-performance collaboration.
