A parameterized general model of water, ice and snow albedo

Shuili Shuiyun Gongcheng Xuebao, 2020
For frozen rivers and lakes with cold climate and frequent snowfall, the albedo of ice cover and snow cover has great influence on climate and ice thickness change.

Climatic Drivers of the Area Burned by Winter Wildfires in Northern Italy

International Journal of Climatology, EarlyView.
This study investigates winter wildfires occurring between November and April in northern Italy over the period 2008–2022. By integrating high‐resolution burned‐area data with gridded climatic indices derived from 150 weather stations, it identifies spatial and temporal wildfire patterns, highlights the most fire‐prone mountain areas through pixel ...

Station‐Based Assessment of Sub‐Seasonal Climate Trends in the Tyrolean Alps (Austria)

International Journal of Climatology, EarlyView.
In this study, we quantify the magnitude and significance of sub‐seasonal trends in the Tyrolean Alps (Austria) by collecting, processing and analysing meteorological observations from a dense network of climate stations. Our analysis indicates a warming rate of 0.43°C/dec over 1964–2023, greater sub‐seasonal trend variability when the analysis window ...

Machine Learning‐Based Correction of Reanalysis Surface Radiation Fluxes Using Ground‐Measured Data in the Southern Brazilian Pampa Biome

International Journal of Climatology, EarlyView.
This study demonstrates that ERA5 provides more accurate surface radiation flux estimates than MERRA2 across the Southern Brazilian Pampa. Machine learning models, particularly Random Forest, further improved the precision of reanalysis data for climate applications.

Nanoscale Rear‐Interface Architecture Enables 36.2 mA cm−2 Photocurrent in Ultrathin and Bifacial ACIGS Solar Cells Through Light Management

Laser &Photonics Reviews, EarlyView.
An array of SiOx nanopillars is developed on ITO transparent rear contacts through nanoimprint lithography to promote light scattering in 500–600 nm bifacial ACIGS solar cells. This architecture increases the short‐circuit current density by 7.8 and 7.6 mA cm−2 under front (up to 36.2 mA cm−2) and rear illumination, respectively, offering a scalable ...

Aerosol and non-aerosol drivers of regional trends in top-of-atmosphere albedo over 2002–2020

Environmental Research Letters
Climate change responds to, and in turn modifies, trends in the Earth’s top-of-atmosphere (TOA) albedo. These trends are caused in particular by anthropogenic aerosol-radiation and aerosol-cloud interactions, as well as by non-aerosol feedbacks involving

How well do the regional atmospheric and oceanic models describe the Antarctic sea ice albedo? [PDF]

The Cryosphere
We 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 ...

Etude d’un dosimètre individuel passif multi-élément pour la dosimétrie des neutrons

, 2017
La dosimétrie individuelle des neutrons est actuellement effectuée à partir de méthodes peu satisfaisantes, soit par l’utilisation d’émulsions nucléaires qui sont “aveugles” pour les énergies inférieures à 1.5 MeV, soit par la mise en œuvre de détecteurs

An Open Database of Lunar Regolith and Simulants Properties

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Lunar regolith, the layer of unconsolidated material covering the Moon's surface, is central to the science and technology developed for the Moon, notably related to in‐situ science investigations, resource utilization, surface infrastructure, and mobility systems.
