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.

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.

Synergistic benefits of agrivoltaics for grape production and solar energy efficiency in a Mediterranean vineyard

PLANTS, PEOPLE, PLANET, EarlyView.
Grapevine production is increasingly challenged by global warming, with global wine output falling to a six‐decade low in 2024. At the same time, the vine and wine sector faces growing pressure to reduce its carbon footprint. Agrivoltaics, which integrates solar photovoltaic (PV) modules into plant production systems, offers a potential pathway to ...

Land Surface Albedo

, 2012
The land surface albedo, i.e., the fraction of solar radiation scattered backward by land surfaces, results from complex nonlinear radiation transfer processes determining the amount of radiation that is scattered by the vegetation and its background ...

Evaluation of Arctic Land Snow Cover Characteristics, Surface Albedo, and Temperature during the Transition Seasons from Regional Climate Model Simulations and Satellite Data

Advances in Meteorology, 2014
This paper evaluates the simulated Arctic land snow cover duration, snow water equivalent, snow cover fraction, surface albedo, and land surface temperature in the regional climate model HIRHAM5 during 2008–2010, compared with various satellite and ...

Areal-Averaged Spectral Surface Albedo in an Atlantic Coastal Area: Estimation from Ground-Based Transmission

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 ...

Climate‐smart land management: Greenhouse gas outcomes and social and economic pathways to adoption

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change poses one of the greatest threats to natural and working lands, reducing the resilience of agricultural and forest productivity. Because land management is a leading source of greenhouse gas (GHG) emissions, climate‐smart management practices are being implemented to reduce net emissions while sustaining yields.

Global-Scale Comparison of MISR and MODIS Land Surface Albedos [PDF]

Journal of Climate, 2011
AbstractThe Moderate Resolution Imaging Spectroradiometer (MODIS) white-sky surface albedos are compared with similar products generated on the basis of the Multiangle Imaging SpectroRadiometer (MISR) surface bidirectional reflectance factor (BRF) model parameters available for the year 2005.

Further development of adaptive parameter tuning in the numerical weather prediction models of Deutscher Wetterdienst

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The introduction of adaptive parameter tuning in the numerical weather prediction models of DWD in 2022 substantially improved the forecast quality of near‐surface variables like 2‐m temperature and 2‐m humidity. Since 2023, refinements and extensions, primarily affecting the surface evaporation and its diurnal cycle, have led to further advances ...

Retrieval of Land Surface Albedo from Satellite Observations: A Simulation Study

Journal of Applied Meteorology, 1998
Land surface albedo is a critical parameter affecting the earth's climate and is required by global and regional climatic modeling and surface energy balance monitoring. Surface albedo retrieved from satellite observations at one atmospheric condition may not be suitable for applicati to other atmospheric conditions.
