Spatial and temporal variations of the surface albedo and other factors influencing Urumqi Glacier No. 1 in Tien Shan, China

Journal of Glaciology, 2017
Glacier albedo controls the surface energy budget, the variability of which affects the glacier surface melt rate and, in turn, impacts the mass balance of the glacier.

Simulations of Photovoltaic Systems on Different Types of Ships in Sweden: Solar Energy Generation, Comparison to Energy Consumption, and Reduction of CO2 Emission

Energy Science &Engineering, EarlyView.
Investigation of the potential of using solar cells on different types of ships, to see how it reduces energy consumption and emissions of carbon dioxide (CO2). From the reduction in fuel consumption, the fuel cost reduction was estimated, and an approximate payback time for the solar cell system was calculated.

The Estimation of Surface Albedo from DSCOVR EPIC

Remote Sensing, 2020
Surface albedo is an important parameter in climate models. The main way to obtain continuous surface albedo for large areas is satellite remote sensing. However, the existing albedo products rarely meet daily-scale requirements, which has a large impact

A simple model for predicting snow albedo decay using observations from the Community Collaborative Rain, Hail, and Snow-Albedo (CoCoRAHS-Albedo) Network [PDF]

, 2017
The albedo of seasonal snow cover plays an important role in the global climate system due to its influence on Earth’s radiation budget and energy balance.

Albedo and laser threshold of a diffusive Raman gain medium

, 2010
The diffuse reflectance (albedo) and transmittance of a Raman random gain medium are calculated via semi-analytic two-stream equations with power-dependent coefficients. The results show good agreement with the experimental data for barium nitrate powder.

Mars Express measurements of surface albedo changes over 2004 - 2010 [PDF]

, 2015
The pervasive Mars dust is continually transported between the surface and the atmosphere. When on the surface, dust increases the albedo of darker underlying rocks and regolith, which modifies climate energy balance and must be quantified.

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 ...

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

Energy 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

Uvb surface albedo measurements using biometers [PDF]

Revista Brasileira de Geofísica, 2008
This work describes ultraviolet-B albedo measurements performed over several surfaces and different atmospheric conditions. These results provide a complement to previous studies as Blumthaler & Ambach (1988), widely used as albedo reference for the main UV radiative transfer models.
