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 ...

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.

Collocated broadband surface albedo and surface type fractions aircraft observations during HALO-(AC)3 flight P5_232_HALO_2022_2203291002

, 2023
During the HALO-(AC)3 campaign conducted in spring 2022, a downward-looking commercial digital cameras equipped with a 180° - fisheye lens was installed on the aircraft Polar 5. The images were used to derive the surface type fractions of snow/white ice,

Temporal PV‐Power of Rooftops and Facades in Urban Areas Based on Ray Tracing

Progress in Photovoltaics: Research and Applications, EarlyView.
In this contribution, we develop an analytical model to calculate the time‐resolved power of PV‐systems on facades, flat roofs, and pitched roofs in an urban area as a function of a full‐load hour threshold. ABSTRACT Distributed photovoltaics (PV) can significantly contribute to the reduction of carbon emissions in urban energy systems.
