How well do the regional atmospheric and oceanic models describe the Antarctic sea ice albedo? [PDF]
The CryosphereWe assessed how well regional climate models (HCLIM, MAR, RACMO), ocean models (MetROMS-UHel, NEMO), and ERA5 reanalysis simulate Antarctic sea ice albedo, snow, and ice thickness, using in situ data from field campaigns (ISPOL, Weddell Sea, in December ...

Long‐Term Variability and Spatial Differentiation of the Frost‐Free Period in Iceland
International Journal of Climatology, EarlyView.Warming in Iceland (May–September) is expressed as fewer Tmin < 0°C days in the interior and more Tmin > 0°C days along the coasts. ABSTRACT Climate change in subarctic regions leads to significant transformations in thermal conditions; however, the long‐term variability of the frost‐free season (FFS)—and consequently, the growing period—remains poorly

Résolution de la stéréophotométrie par apprentissage [PDF]
, 2012 Session "Posters"National audienceNous montrons dans cet article comment résoudre la stéréophotométrie par apprentissage. L'idée de base consiste à insérer une sphère dans la scène dont on souhaite retrouver le relief, et à recouvrir la sphère et la ...

Répercussions météorologiques découlant de modifications naturelles ou délibérées de la surface. Principes généraux et prospectives, région de la Baie James [PDF]
, 1974 Les régions arctique et subarctique se prêtent merveilleusement à l'expérimentation du fait de la grande variabilité saisonnière de l'état de leurs surfaces glacées et neigeuses.

Land Degradation &Development, EarlyView.ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Atmosphere, 2017 Tower-based data combined with high-resolution satellite products have been used to produce surface albedo at various spatial scales over land. Because tower-based albedo data are available at only a few sites, surface albedos using these combined data ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Using a large and novel array of instruments on five rockwalls in northern Gaspesia, their respective surface energy balances were calculated and their thermal regimes were measured and modeled to depths exceeding the seasonal frost penetration.

Sensitivity of mountain glacier mass balance to changes in bare-ice albedo
Annals of Glaciology, 2017 Albedo is an important parameter in the energy balance of bare-ice surfaces and modulates glacier melt rates. The prolongation of the ablation period enforces the albedo feedback and highlights the need for profound knowledge on impacts of bare-ice ...
