Ce papier présente l'utilisation d'un simulateur atmosphérique reposant sur un modèle de prévision météorologique à haute résolution pour reproduire des statistiques d'atténuations due à la pluie pluriannuelles en bande Ka en Guyane française. Les résultats obtenus à l'aide de ce modèle sont comparés d'une part aux données expérimentales disponible...
The Oxygenated Compounds in the Tropical Atmosphere: Variability and Exchanges (OCTAVE) campaign aimed to improve the assessment of the budget and role of oxygenated volatile organic compounds (OVOCs) in tropical regions, and especially over oceans, relying on an integrated approach combining in situ measurements, satellite retrievals, and modeling...
The solar proxy 10Be, measured in natural archives, has previously been assumed to lag solar activity by 1–2 yr. This reflects its residence time in the stratosphere where its main source lies. This study, based on a 30-yr global model simulation of the atmospheric transport of 10Be, shows that the stratospheric fraction of production varies signif...
Several recent studies have shown the width of the tropical belt has increased over the last several decades. The mechanisms driving tropical expansion are not well known and the recent expansion is underpredicted by state-of-the art GCMs. We use the CAM3 GCM to investigate how tropical width responds to idealized atmospheric heat sources, focusing...
