Towards CMIP6 internationally coordinated climate modeling experiments: the role and use of modeling and observation research infrastructuresPICO session
Convener: Sylvie Joussaume  | Co-Conveners: Abad Chabbi , Helen Glaves , Francesca Guglielmo , Sanna Sorvari

The Coupled Model Intercomparison Project (CMIP) coordinates the design and distribution of global climate model simulations of the past, current, and future climate, thus becoming one of the foundational elements of climate science. Now in its sixth phase, CMIP addresses three broad questions related to:
- The Earth system’s response to forcing,
- The origins and consequences of systematic model errors,
- The assessment of future climate changes, given uncertainties in variability, predictability, and scenarios.
CMIP is made possible by the adoption of common standards, the coordination of science and infrastructures, and by the documentation of models, experiments, and results.

This session aims at exploring the role and use of research infrastructures for both model data and observations in preparation for CMIP6, with a particular focus on Earth’s climate system model evaluation. Descriptions of the state-of-the-art of the existing modeling, observation and experimental infrastructures and of the cooperation already in place will be welcome. Demonstrations of the impacts of the use of these infrastructures in scientific research on Earth system/climate are expected. This screening and scoping phase goes beyond the technical issues that guarantee interoperability among RIs, rather concentrating on the scientific common challenges. It concerns all the components of the climate system atmosphere, ocean, and land.
This session is proposed within the frame of ENVRIplus, a Horizon 2020 project bringing together European Environmental and Earth System Research Infrastructures, aiming at providing common solutions to shared challenges.
