About the LGGE

About 150 persons work at the Laboratoire de Glaciologie et Géophysique de l’Environnement (LGGE), created in 1958. The research topicsd of the laboratory are snow and ice, glaciers, climate - atmosphere, ice and ocean - and the environment.

From the directors

In more than 50 years, the LGGE has built its scientific reputation on studies of the climate and the composition of the atmosphere. Our studies of the past climate and environmental conditions rely to a large part on the analysis of snow and ice as archives of the past. But this laboratory has competitive know-how in many other domains, such as the study of the mechanical and physical properties of snow and ice, chemical exchanges at the snow-air interface or remote sensing over snow and ice. Our research combines analytical and technological developments with numerical approaches in diverse areas, from the atmosphere to ice flow and, more recently, to the oceans. The Arctic and Antarctic are privileged work areas, but our work extends to mountain regions (studies of glaciers in the Alps, the Andes and the Himalayas, atmospheric pollution in the Alps and the Himalayas- and the oceans (role of the oceans in the climate system, medium-term prediction of ocean circulation). These studies contribute to the understanding of important scientific problems which are often societal issues such as the greenhouse effect, climate variability, mass balance of the cryosphere and sea level, pollution on global and regional scales, or glacial risks.

At LGGE, more than 150 persons — scientists, university teachers, students, engineers, technicians — work together in the laboratory or the field on subjects of major societal interest.

Scientific priorities of the LGGE

Research at LGGE focuses on three priorities:

  • Past and present evolution of the atmospheric composition and study of feedbacks between atmospheric chemistry and climate ;
  • The polar regions and their past, present and future impact on the climate system ;
  • Vulnerability of glaciers and snow cover in mountain regions under climatic change and its impacts on water resources.
  • Ocean processes and their effects on the climate system, notably via ocean-atmosphere-ice interactions

In the field

Every year, many LGGE scientists, engineers and technicians carry out field work in the cold places of our planet: Arctic, Antarctic, Alps, Himalaya, Andes.
