Validation of Space-Based Albedo Products from Upscaled Tower-Based Measurements Over Heterogeneous and Homogeneous Landscapes

Remote Sensing, 2020
Surface albedo is a fundamental radiative parameter as it controls the Earth’s energy budget and directly affects the Earth’s climate. Satellite observations have long been used to capture the temporal and spatial variations of surface albedo

A parameterization of ocean surface albedo

Geophysical Research Letters, 2004
Measurements at a sea platform show that the ocean surface albedo is highly variable and is sensitive to four physical parameters: solar zenith angle, wind speed, transmission by atmospheric cloud/aerosol, and ocean chlorophyll concentration. Using a validated coupled ocean‐atmosphere radiative transfer model, an ocean albedo look up table is created ...

Restoring Trust: Rebuilding the Forest Carbon Credit System Through Scientific Rigor

Biological Diversity, EarlyView.
ABSTRACT As pivotal nature‐based climate solutions (NbCS), forests are increasingly recognized for their climate mitigation potential. However, this potential is undermined by fundamental flaws in current carbon credit systems. Our analysis identifies four interconnected systemic challenges: (1) subjective additionality assessments arising from ...

Re-understanding of land surface albedo and related terms in satellite-based retrievals

Big Earth Data, 2020
Land surface albedo is a critical variable in determining surface energy balance, and regulating climate and ecosystem processes through feedback mechanisms. Therefore, climatic modelers and radiative monitoring require accurate estimates of land surface

A mosaic of microclimates: biodiversity outcomes and wildlife habitat potential in large‐scale solar facilities

Biological Reviews, EarlyView.
ABSTRACT The rapid global expansion of photovoltaic (PV) solar facilities, now comprising nearly 80% of the recent and projected growth of renewable electricity, represents one of the most significant land‐use changes of the 21st century. While PV facilities are critical for decarbonising energy systems, their large spatial footprint and infrastructure

Reflecting on surface albedo and climate

Climate Research
Changes in land use and vegetation cover influence both land and water surface biogeochemical as well as biogeophysical processes. While the major emphasis has been on how these changes influence the biogeochemical processes underlying carbon sequestration and greenhouse gas (GHG) emissions, recent evidence suggests that biogeophysical effects ...

Land Surface Albedo Estimation from Chinese HJ Satellite Data Based on the Direct Estimation Approach

Remote Sensing, 2015
Monitoring surface albedo at medium-to-fine resolution (<100 m) has become increasingly important for medium-to-fine scale applications and coarse-resolution data evaluation.

Surface Albedo and Snowline Altitude Estimation Using Optical Satellite Imagery and In Situ Measurements in Muz Taw Glacier, Sawir Mountains

Remote Sensing, 2022
Glacier surface albedo strongly affects glacier mass balance by controlling the glacier surface energy budget. As an indicator of the equilibrium line altitude (ELA), the glacier snowline altitude (SLA) at the end of the melt season can reflect ...
