Abstract Despite knowledge of the presence of the Tibetan Plateau (TP) in reorganizing large-scale atmospheric circulation, it remains unclear how surface albedo darkening over TP will impact local glaciers and remote Asian monsoon systems. Here, we use a coupled land-atmosphere global climate model and a glacier model to address these questions. U...
Silvopastoral systems (SPSs) have been shown to improve ecosystem resilience and provide sustainable land management solutions in the Sahel. However, accurately estimating the contribution of Sahelian ecosystems to the overall greenhouse gas (GHG) balance is a challenge, in particular the magnitude of carbon dioxide (CO2) and nitrous oxide (N2O) em...
Abstract Lake surface water temperature (LSWT) is a key parameter in lake energy budget and is highly vulnerable to climate change. However, the long‐term trends in LSWT across China and their driving factors remain uncertain. Here, we used a calibrated lake model to simulate LSWT over 1979–2018 for 91 large lakes (>100 km 2 ) across China. Simulat...

The pilot study CCQM-P204 was aimed at evaluating the level of compatibility of laboratories' measurement capabilities to value assign isotope ratios in samples of pure CO2 gas, expressed as isotope delta values relative to the relevant international scale: δ13CVPDB and δ18OVPDB-CO2. Pure CO2 gas samples were prepared by the BIPM in batches of 10 s...
Abstract. The EPICA (European Project for Ice Coring in Antarctica) Dome C (EDC) ice core drilling in East Antarctica reaches a depth of 3260 m. The reference EDC chronology, the AICC2012 (Antarctic Ice Core Chronology 2012), provides an age vs. depth relationship covering the last 800 kyr (thousands of years), with an absolute uncertainty rising u...
Cette présentation croise plusieurs projets de recherches menés en géographie physique et en géoarchéologie permettant de comprendre l’implication d’évènements extrêmes historiques sur la transformation des paysages côtiers et sur l’évolution des sociétés humaines littorales anciennes. L’échelle temporelle considère l’évolution de ces processus phy...
Des mesures de résonance magnétique protonique ont été acquises de manière répétée lors d'un suivi de fonte de neige sur le bassin versant du Strengbach (site de l'Observatoire Hydro-Géochimique de l'Environnement, Vosges) pendant l'hiver 2021. Nous utilisons ces mesures géophysiques pour caractériser les propriétés de la zone vadose, en estimant l...
