Physically based model of the contribution of red snow algal cells to temporal changes in albedo in northwest Greenland [PDF]

open access: yesThe Cryosphere, 2020
Surface albedo of snow and ice is substantially reduced by inorganic impurities, such as aeolian mineral dust (MD) and black carbon (BC), and also by organic impurities, such as microbes that live in the snow.

Selective Optical Properties of Cement for Enhanced Radiative Cooling and Energy‐Efficient Construction Materials

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.

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

open access: yesRemote 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 ...

Maximizing Energy Generation in Agrivoltaic Systems: A Study of Bifacial and Monofacial Modules With Consideration of Module Height and Albedo Impact

open access: yesEnergy Science &Engineering, EarlyView.
This study evaluates the performance of bifacial and monofacial PV modules in agrivoltaic systems using PVsyst simulations. Real albedo measurements from a wheat field were incorporated to ensure realistic results. Bifacial modules demonstrated a 19.46% increase in energy yield compared to monofacial ones.

Integrating Remote Sensing and Machine Learning for Enhanced Surface Urban Heat Island Analysis and Its Impact on Building Energy Demand

open access: yesEnergy Science &Engineering, EarlyView.
Satellite (MODIS) mapping links Urban Heat Island (UHI) intensity to city‐scale energy demand—higher daytime cooling demand and altered nighttime heating demand—supporting targeted mitigation and planning. ABSTRACT This study examines the surface urban heat island (SUHI) effect on building energy consumption in Tehran from 1998 to 2024, utilizing MODIS

Estimating the daily mean blue-sky land surface albedo on the Tibetan Plateau using convolutional neural network

open access: yesInternational Journal of Digital Earth
Surface albedo is a critical indicator of Earth’s ability to reflect solar radiation, influencing energy balance and climate dynamics. Research on blue-sky albedo on the Tibetan Plateau has often focused on clear-sky conditions, overlooking seasonal snow

Observations and modeling of areal surface albedo and surface types in the Arctic [PDF]

open access: yesThe Cryosphere
An accurate representation of the annual evolution of surface albedo of the Arctic Ocean, especially during the melting period, is crucial to obtain reliable climate model predictions in the Arctic. Therefore, the output of the surface albedo scheme of a
