Charles Amory, Researcher, CNRS
My work is focused on advancing our understanding of the interactions between ice sheets and the climate system. Through the development of models and the acquisition of in-situ observations, I aim to document the evolution of the polar snowpack, which plays a crucial role in mediating interactions between the warming atmosphere and the ice sheets experiencing mass loss
Laurent Arnaud, Research Engineer, CNRS
I study the snow cover on the surface of the polar ice caps and develop new instruments to characterize the optical and physical properties of snow. Our current challenge is to access the small and large scale spatial variability of snow cover properties. To do this, I participate in many field missions in polar regions and integrate our various sensors on drones. At the same time, I’m leading the UAV-IGE project, whose objective is to promote the use of UAVs in the various IGE themes.
Fanny Brun, Researcher, IRD
My research work focuses on the measurement of mass changes of mountain glaciers. The originality of my approach is to combine both field measurements (to better understand glaciological processes) and spatial remote sensing measurements (to apprehend changes on a regional scale). I am particularly interested in the glaciers of Asia, the Andes and the Alps.
Claire Brutel-Vuilmet, Lecturer, UGA/IUT1
My research concerns the modeling of the climate system in polar, subarctic or high mountain areas. I am more particularly interested in the cryosphere : its feedbacks on the atmosphere, interactions with vegetation, or thermal exchanges with the surface (soil, permaforst...). In the framework of the ESM-SnowMIP model intercomparison project, I am participating in the evaluation of snow models and I am trying to quantify some snow feedbacks on the other components of the climate system.
Victoire Buffet, PhD student
I study the future evolutions of atmospheric rivers (ARs) in Antarctica and their impact on the ice sheet. I am interested in ARs because they have a significant impact on the surface mass balance in Antarctica : positive on the East Antarctic ice sheet, but negative in the West, by transporting heat and humidity. My work aims to improve their detection and representation in climate model projections.
Ian Castellanos Dupuy, PhD student
During my PhD, I study climate change in the Alps with the aim of characterizing its impact on a local scale. To this end, I am using data from a regional climate model that simulates climate change up to the end of the century according to scenarios established by the IPCC. I am particularly interested in the physical causes of seasonal and geographical differences in simulated climate change.
Gabriella Collao Barrios, PhD student
Thomas Condom, Researcher, IRD
I am a hydro-glaciologist. My research focuses on the hydrological cycle in mountain areas (Andes and Alps), where glaciers, impacted by climate change, can play an important role, still little known. My work is based on in-situ and satellite measurements and hydro-glaciological modelling, in order to better understand the interactions between climate variability and the response of hydrological systems at different spatial and temporal scales. I am co-director of the GREAT ICE International Joint Laboratory (IRD) which is a unique global network of researchers from North and South interested in glaciology-hydrology-climate-biodiversity relationships in the tropical Andes.
Jean-Pierre Dedieu, Researcher, CNRS
My research activities focus on the study of the physical properties of snow and ice by spatial remote sensing for the analysis of snow-glacial processes (space-time dynamics, water balances) in relation to climate parameters measured at the regional scale. The sensors used are in active radar (SAR) or optical mode and the resituated data are compared to in-situ measurements in order to model the target behaviours (albedo, snow depth, density). The application sites and international scientific programs are located in the following locations
Gilles Delaygue, Lecturer, UGA
My research focuses on climate variability, its reconstruction methods, and its origins, in particular the role of solar activity in the modulation of this activity in the North Atlantic. I teach Earth sciences in bachelor and master degrees at UGA.
Jhan Carlo Espinoza, Assistant Researcher, IRD (MOPGA)
My research focuses on understanding the impacts of climate variability and change on hydrology in the Amazon basin, with a special emphasis on the Andean-Amazon region. Since 2018 I am leading the AMANECER (Amazon-Andes connectivity) project of the Make our Planet Great Again program. In this framework, I am more interested in the climatic continuity between the Amazon and the Andes by considering the impacts of climate change and land use changes in the Amazon. I am a member of the steering committee of the regional hydro-climatic program ANDEX (GEWEX) and of the Scientific Panel for the Amazon (SDSN, United Nations).
Xavier Faïn, Researcher, CNRS
After a decade devoted to the study of paleo-climates based on glacial archives, I am currently redirecting my research activities towards the study of climatic variability in mountain regions.
Vincent Favier, Lecturer (Assistant Physist), OSUG-UGA
My research focuses on the measurement and regional scale modeling of the Antarctic surface energy and mass balances (GLACIOCLIM-SAMBA). Outside Antarctica, my research is focused on the link between climate and glacier melting, with a focus on the sub-Antarctic region (Kerguelen archipelago) and Patagonia.
Hubert Gallée, Senior Scientist, CNRS
I am the developer of the Regional Atmospheric Model (MAR) and I am particularly interested in the applications of this model for the study of the hydrological cycle, the surface mass balance of Antarctica, including the transport of snow by wind. I am also currently interested in the rainfall regime of West Africa.
Audrey Goutard, PhD student
My thesis work focuses on the study of rain and meltwater on the surface of mountain glaciers (Bolivia, Nepal, and the Alps), specifically its impact on the energy and mass balance. To do this, I am developing an approach to account for liquid water on the ice surface in the SURFEX-ISBA Crocus model and am also conducting field measurements related to albedo.
Bruno Jourdain, Lecturer (Assistant Physist), UGA, OSUG
I recently joined the Service National d’Observation GLACIOCLIM in which I participate in the monitoring of mountain glaciers.
Clémentine Junquas, Researcher, IRD
I study the spatial and temporal variability of precipitation in the tropical Andes and seek to better understand the local, regional and global atmospheric processes that influence Andean precipitation. I use among others the regional climate model WRF (Weather Research and Forecasting) in order to perform climate simulations at high spatio-temporal resolution. I am particularly interested in high glacial watersheds and valley processes in the Amazon-Andes transition zone.
Gerhard Krinner, Senior Scientist, CNRS
My work in polar climate modeling focuses on surface processes (snow, permafrost) and ice sheet mass balance. I also work on error correction methods for climate simulations. Furthermore, I am currently heavily involved in the work of the IPCC for the preparation of the 6th Assessment Report (2021/2022).
Anne Letreguilly, Lecturer, UGA
My research focuses on the analysis and spatialization of ice mass balance data. I teach in L1 Life Sciences and L1 Chemistry-Biochemistry (computer science, co-responsibility of these Teaching Units) but also in L3 Earth and Environmental Sciences, and L3 Physics - Earth and Environmental Sciences - Mechanics (glaciology).
Martin Ménégoz, Researcher, CNRS
My research activity focuses on climate variability. I use climate models and observational datasets to study the climate response to external forcings : natural (such as volcanic eruptions), and anthropogenic (such as greenhouse gases and atmospheric aerosols). My investigations concern the climate of the past centuries as well as projections for the next century. I am particularly interested in the interactions between the atmosphere, the hydrosphere and the cryosphere over mountainous areas.
Ignacio Palomo, Researcher, IRD
I work on mountain socio-ecological systems, mainly on their challenges within the Anthropocene and the potential of nature-based solutions to address them. In particular, I study the interactions between biodiversity, ecosystem services and social equity.
Ghislain Picard, Professor, UGA
I study the snow cover in the polar regions (Antarctica, Arctic) using satellite observations and in-situ instruments. My aims is to detect and understand snow changes induced by the climate. For this, I’m interesting in measuring and modeling the dynamics of the albedo, grain size, temperature, impurities content and all the other snow properties that somehow play a role on the Surface Energy Balance. I have been involved in many polar field campaigns and I have developed several radiative transfer models working in the optical and microwave ranges to understand the satellite signal and compute the surface radiative fluxes.
Jean Emmanuel Sicart, Researcher, IRD
I am interested in the interactions between climate and glaciers and snow-covered mountains, especially in the Central Andes and the Alps. The analysis of the climatic forcings that control glaciers involves the study of atmospheric energy flows. I am therefore interested in the measurement (and associated problems) and simulation (and associated problems) of these flows that provide energy for melting ice or snow.
Delphine Six, Professor (Physicist), OSUG-UGA
My research activities focus on the monitoring of mountain glaciers (mainly in the Alps) as an emblematic indicator of climate change. My research is based on a set of observations declined within the National Observation Service GLACIOCLIM, Service that I carry and coordinate. Today, my research activities are very largely oriented towards society with many applications for hydroelectric companies, tourism companies, government services, as to the future evolution of mountain glaciers.
Patrick Wagnon, Senior Scientist, IRD
As a field glaciologist specializing in the Himalayas, I have set up a glacier observation network in India since 2002 and in Nepal since 2007, within the framework of the GLACIOCLIM observatory (https://glacioclim.osug.fr/). My research focuses on glacier mass balances in these regions, and their relationship with the current climate. I work in collaboration with local teams, and lead the High Mountains of Asia project at the IGE.
