IRICLIM (Integrated Research Insight into Climate Risks) project

The IRICLIM project, which will run from 2026 to 2029, is a research project coordinated by Météo-France as part of the Risks Programme (PEPR IRIMA). Its overall objective is to improve the data, tools and services needed to anticipate these changes and limit their impacts on regions and populations. IRICLIM will focus in particular on understanding and managing risks linked to weather conditions and climate change in mainland France and Corsica. IRICLIM is developing a new mapping method, based on a collaborative and multidisciplinary approach, to incorporate the impacts of global warming. This project brings together key stakeholders whose aim is to improve the assessment of climate‑related disasters. Innovative methods will be developed to (1) refine risk mapping by integrating multi‑source data (satellite, geological, meteorological, climatic) and machine learning/artificial intelligence techniques,(2) improve methods for anticipating flash floods, wildfires and hydrotechnical droughts by reducing uncertainties and refining spatial and temporal scales,(3) assess the vulnerabilities of two regions by cross‑referencing physical data with socio‑economic factors, to enable more targeted risk management (lowlands: Centre‑Val de Loire region / mountains: Isère department).

Background and expectations

CNRM has developed the ISBA land surface model within SURFEX, an operational modelling platform capable of simulating terrestrial water and carbon fluxes. ISBA can be coupled with various atmospheric and hydrological models, and it incorporates a global land data assimilation system (LDAS-Monde). LDAS-Monde uses an extended Kalman filter to assimilate satellite data and analyse soil moisture and vegetation biomass at spatial resolutions ranging from 1 to 25km. Initially, the postdoctoral fellow will implement LDAS over mainland France and Corsica, utilising atmospheric forcing from the AROME numerical weather prediction (NWP) model. Relevant land surface predictors of drought, such as soil moisture at various depths, will then be used to inform decision‑support services relating to climate risks. The results will be published in open literature. The postdoctoral fellow will also contribute to the management of cross‑cutting activities to implement a multi‑risk approach that relies on interdisciplinarity.
