Extreme Events : Statistics, Impacts & Regionalization

The “Extremes-Statistics-Impacts-Regionalization” (ESTIMR) team

The “Extremes-Statistics-Impacts-Regionalization” (ESTIMR) team has for main objectives the understanding and the modelling of the climate and environmental variability at various spatial scales – from very large structures related to the atmospheric dynamics, to very local phenomena – and at various temporal scales – for the study of past climates, present processes and future climate evolutions. In this very wide context, one of the strengths of ESTIMR is based on the use and the development of state-of-the-art statistical models adapted to climate problems, through a strong multidisciplinary interaction between climatology, modelling and statistics.

Research topics

In a non-exhaustive way, the main research axes of the ESTIMR team are (interdependent). [Click on the links for more information].

-Detection & Attribution of climate extreme events

-Downscaling & Bias correction of climate simulations

-Statistical mechanics and dynamical systems approach for climate.

-Science for climate Services.


These main axes offer a large variety of applications.

-Evaluations of global and regional climate models (i.e., GCMs and RCMs/SDMs).

-Regional projections of (past, present, future) large-scale climate simulations.

-Detection/attribution of climate change (e.g., on extremes).

-Impacts of climate changes on different systems/domains (e.g., hydrology, renewable energy, ecology, etc.).

-Reconstruction of past climates (last millennium, last glacial maximum, etc.).

Moreover, most of the statistical models and tools developed in the team are made freely available to the scientific community through R packages.

Therefore, the ESTIMR team can be seen as at the interface between fundamental climate researches and some societal issues (related to the impacts of climate changes) in developing statistical tools acting as bridges between the two, and available to the scientific community and the society.
