Led by Meteorological and Environmental Earth Observation SRL (MEEO), Work Package 1 aims to establish a comprehensive database and implement data management principles and guidelines. It will ensure full adherence to the data management plan while leveraging Earth observation data for modelling the carbon cycle of terrestrial ecosystems and extreme events. These efforts will enhance data accessibility and support informed decision-making in climate research.

Led by Barcelona Supercomputing Center (BSC), Work Package 2 focuses on extending and improving past, present, and future high-resolution land use and land cover maps. It will also create a long-term, time-varying dataset of the leaf area index and develop a land management intensity. Additionally, WP2 will generate a new biomass productivity map of managed and unmanaged ecosystems, contributing to a more accurate assessment of the contribution of management to the carbon budget.

Led by the European Centre for Medium-Range Weather Forecasts (ECMWF), Work Package 3 will develop multivariate land data assimilation capabilities for Earth system models by integrating machine learning-based and process-based observation operators. These advancements will be implemented in the Integrated Forecast System to improve climate modelling. WP3 will also provide recommendations on optimal combinations of assimilated vegetation satellite observations to maximise carbon and water surface flux prediction performance while evaluating the added value of multivariate satellite datasets.

Led by Imperial College London (ICL), Work Package 4 aims to develop and test a new implementation of the P model, driven by satellite retrievals of solar-induced fluorescence. It will incorporate recent findings on the adaptive nature of gross primary production responses to temperature and soil moisture. Additionally, WP4 will improve and reconcile global top-down and bottom-up inventories of isoprene, test modelled predictions of non-photochemical quenching, and enhance understanding of vegetation responses to extreme events such as heatwaves, droughts, and wildfires.

Led by Fondazione Centro Euro-Mediterranneo sui Cambiamenti Climatici (CMCC), Work Package 5 focuses on improving the coupling between the carbon cycle and the water, energy, and nitrogen cycles. It will characterise land surface model uncertainties related to land surface parameters and assess enhanced versions of Earth system models that incorporate the developed carbon cycle processes. Furthermore, WP5 will provide guidelines for land carbon cycle representation in future Earth System Models developments, ensuring more accurate climate projections.

Led by the University of Reading (UREAD), Work Package 6 aims to design a hierarchy of uncoupled and coupled land-atmosphere experiments that build on the land surface developments in WP5. These experiments will demonstrate the integrated benefits of these advancements through both offline global simulations (driven by reanalyses) and coupled  Earth system models. By refining model integration, WP6 will enhance the reliability of climate predictions.

Led by Pensoft, Work Package 7 aims to maximise the project’s impact through the planning and implementation of communication, dissemination, and exploitation strategies. It will ensure that project results and generated knowledge in the field of carbon stocks and fluxes are effectively shared with stakeholders. WP7 will also develop a plan for dissemination, exploitation, and communication of results to secure the project's long-term impact and legacy while identifying collaboration pathways with existing projects, networks, and initiatives.

Led by Fondazione Centro Euro-Mediterranneo sui Cambiamenti Climatici (CMCC), Work Package 8 is responsible for overall project coordination and management. This includes administrative and financial oversight, quality assurance, risk management, and progress monitoring. By ensuring efficient project execution, WP8 will support the successful delivery of all work packages.
