The ESYDA division has the mission of developing numerical models and implementing their integration finalized to the construction of a state-of-the-art Earth System model (ESM) including its physical components, biosphere and cryosphere, capable of driving the international debate on climate and environmental research and, at the same time, satisfying the needs of CMCC’s research and operational activities. In addition, ESYDA has the task of developing the most advanced and innovative data assimilation systems, that leverage cutting-edge techniques and methodologies allowing the production of high–quality earth system analyses, enabling a deeper understanding of the state of the Earth System and providing the best initial conditions for skillful and reliable climate forecasts.

ESYDA will apply the modeling and data assimilation systems developed to the production of simulations, climate change projections and analyses of the ocean, atmosphere, cryosphere and land, seeking to reduce uncertainties in our knowledge of the future evolution of the Earth System and biogeochemical cycles that characterize it.

ESYDA also aims to improve conventional models using Machine Learning (ML) in a suite of approaches, for example by embedding ML components within physics-based models, coding hybrid models and emulators, developing new parameterizing for sub-grid processes.
