Data

Observations et modélisation

Les observations du climat par satellite fournissent des données qui permettent de valider et d’améliorer la qualité, la crédibilité et la valeur des modèles prédictifs. L’ESA CCI comprend plusieurs projets visant à renforcer la collaboration entre les communautés de l’observation de la Terre et de la modélisation du climat, à faciliter l’exploitation scientifique des données climatiques issues de satellites pour leur assimilation dans les modèles, le calibrage et le paramétrage des modèles, ce qui permettra d’améliorer la compréhension et les prévisions.

L’ESA héberge également le bureau international du projet CMIP (projet d’intercomparaison des modèles couplés), qui coordonne les activités de modélisation, de données et d’observation à l’échelle mondiale, sous l’égide du Programme mondial de recherche sur le climat.

Observations and climate modelling research

These research projects facilitate the development, and utilisation, of satellite-based climate data products (ECVs) to better constrain and validate climate models used to understand past and predict future climate change.

CMIP forcing dataset projects

These project are developing enhanced observation-driven climate forcing datasets as inputs to the Coupled Model Intercomparison Project (CMIP) and improve the accuracy of historical climate simulations and future projections used in IPCC assessments.

CMIP forcing - GHG concentrations

This project is developing new methods to create climate model inputs from ice cores, ground-based and satellite observations to improve greenhouse gas data input to Coupled Model Intercomparison Project.

CMIP forcing - volcanic

The project is producing stratospheric aerosol optical properties and volcanic stratospheric sulphur emission datasets from 1750 to present-day. They are key for climate model simulations run as part of the Coupled Model Intercomparison Project and feed into IPCC assessments.
