Programme Description

Horizon Europe is the European Union (EU) funding programme for the period 2021 – 2027, which targets the sectors of research and innovation. The programme’s budget is around € 95.5 billion, of which € 5.4 billion is from NextGenerationEU to stimulate recovery and strengthen the EU’s resilience in the future, and € 4.5 billion is additional aid.

Advancing Earth System Models to increase understanding of Earth system change

Summary

ESMs are the main tools used to assess future changes in the climate system.

Their resolution and realism have increased over the last two decades. Despite these advances, there are still several poorly understood and simulated processes, interactions and feedbacks that limit their ability to provide accurate predictions and forecasts of global and regional Earth system change, and to help understand and quantify future climate variability.

A particular challenge is how variability interacts with extreme events (including complex ones), particularly in relation to rainfall and water availability (both excess and scarcity).

Detailed Call Description

Actions should address all of the following aspects:

  1. Improving the simulation of the coupled Earth system and its sensitivity to natural and anthropogenic forcings, with a better representation of key Earth system and climate feedbacks and processes, including, among others, one or more of the following advances:
    • The interplay between global change, regional climate variability, and changes in climate and weather extremes;
    • Terrestrial-ocean-climate interactions;
    • Coupled climate-carbon-water cycle feedbacks;
    • Coupled climate-ocean-ice interactions;
    • Aerosol-cloud-climate forcing and feedback;
    • Climate-vegetation-fire interactions;
    • Climate-air quality interactions;
    • Interactions between land use scenarios (in terms of changes in the land use and surface, such as those related to carbon dioxide removal, with consequences on the water and carbon cycles, albedo and aerosols) and regional climate.
  2. Increased collaboration across different model development approaches encompassing the range of available model resolutions and model realism.
  3. Bring together and further improve existing and new observational and reanalysis datasets, models, emulators, and analysis tools to facilitate rapid and in-depth bias identification, model calibration and validation, and evaluation and understanding of model simulations.

Actions should exploit the opportunities offered by state of art digital technologies such as machine learning, big data analytics or Artificial Intelligence (AI). They should promote the highest standards of transparency and openness, extending to aspects such as assumptions, protocols, code, and data that is managed in compliance with the FAIR principles. Beneficiaries of EU funding are required to publish results data in open access repositories and/or as annexes to publications, and provide full openness of any new modules, models or tools developed from scratch or substantially improved. Projects should take into account, during their lifetime, relevant activities and initiatives for ensuring and improving the quality of scientific software and code.
