Trusted, high-resolution databases for reliable climate decision

Whether you need climate and hydrological projections, flood indicators, customised data management or proprietary datasets, we apply the same rigorous standards. We use them in our own workflows, ensuring reliable, consistent and actionable information to strengthen your climate-related projects. Our CWF databases provide selected datasets and indicators that can be directly integrated into your models, platforms, and workflows. They are designed to be flexible and scalable. They ensure seamless access to reliable, ready-to-use climate and hydrological information.

Advanced hydrological modelling for climate resilience

Our databases capture the full dynamics of hydrological systems in the context of climate change. Why? Because they are developed using extended and bias-corrected CMIP6 ensembles, regionalised data, and advanced hydrological and flood models. We also use deep learning and hybrid modelling approaches. The aim is to improve the accuracy of hydrological projections and flood simulations, thereby offering a new level of reliability for impact and risk assessments.

The Hydroclimat database planets

Three interconnected databases, built on science and high-performance computing, form the core of Hydroclimat's data ecosystem. They turn complex climate and hydrological data into reliable insights for decision-making.

Climate database

Aeris

Integrates bias-corrected CMIP6 multi-model projections, TRACC indicators, and extreme statistics. Delivers a consistent foundation for impact studies, resilience planning, and climate risk assessments.

Water Database

Hydros

Models discharge and resource availability. Supports sustainable water management and adaptation strategies.

Flood Database

Fluxus

Models runoff, floods, and floodplain dynamics across multiple spatial scales. Provides dynamic floods indicators for planning, and insurance applications.

Together

Aeris, Hydros, and Fluxus form an integrated, interoperable, and scalable data architecture, establishing a world-class benchmark for physical climate risk analysis.

Aeris : The climate
intelligence database

Aeris provides harmonised and bias-corrected climate datasets that enable advanced analysis of climate risks, their impacts and adaptation measures. Aeris is the atmospheric foundation of the Hydroclimat data ecosystem. It links global and regional climate signals to hydrological, environmental and risk modelling frameworks. Aeris also provides actionable climate information for decision-making, harmonised at all spatial scales. This ranges from global climate trajectories to adaptation measures specific to certain French sites, and forms the basis of Hydroclimat's Hydros and Fluxus systems
