• Surface ice texture mapping of Planpincieux glacier reveals spatial mechanical heterogeneities · 2026

  Résumé de la publication : Crystallographic textures or Crystal Preferred Orientations (CPO) of glacier ice significantly influence its mechanical behavior by transferring mechanical anisotropy from the single-crystal scale to the macroscopic scale. However, their spatial variability and impact on fluidity remain poorly constrained in temperate glaciers. This…

• Spatial predictions and uncertainty maps of global fallout radionuclides (137Cs and 239+240Pu) for the Southern Hemisphere · 2026

  Résumé de la publication : This repository contains high-resolution (1 km) spatial datasets for global fallout radionuclides across the Southern Hemisphere (extending to 20°N). The data includes spatial predictions, uncertainty estimates, and model applicability assessments for Cesium-137 () and Plutonium-239+240 () inventories in soil.

• Global projections of aridity index for mid and long-term future based on CMIP6 scenarios · 2026

  Résumé de la publication : This study evaluates and projects global aridity index (AI) and dryland distribution using the FAO Aridity Index based on Penman-Monteith potential evapotranspiration. A multimodel ensemble of 13 CMIP6 models, with a horizontal resolution of 100 km, was selected for analysis. The ensemble was…

• High-resolution modelling of organic aerosol over Europe: exploring spatial and temporal variability and drivers · 2026

  Résumé de la publication : Organic aerosol (OA) is a major component of atmospheric particulate matter (PM), affecting both human health and climate. However, high-resolution estimates of OA exposure needed for exposure analysis remain scarce. Here, we integrate a chemical transport model (CAMx) with a random forest…

• Beryllium 10 in Antarctica over the last seven millennia · 2026

  Résumé de la publication : Since the first measurements of beryllium 10 (10Be) in ice, in the seventies, numerous profiles of this cosmogenic isotope have been obtained both in Antarctica and Greenland. In this article, we focus on Antarctic data, available at nine different sites, covering a…
