Monitoring glacier albedo as a proxy to derive summer and annual surface mass balances from optical remote-sensing data [PDF]

The Cryosphere, 2018
Less than 0.25 % of the 250 000 glaciers inventoried in the Randolph Glacier Inventory (RGI V.5) are currently monitored with in situ measurements of surface mass balance.

Albedo distribution in Lutzow-Holm Bay and its neighborhood

Antarctic Record, 1997
A method has been developed for estimating the filtered narrow band surface albedo with NOAA/AVHRR data, and has been applied to analysis of the surface albedo distribution in Lutzow-Holm Bay and its neighborhood, Antarctica, in 1990.

A fusion method to accurately derive all-sky surface shortwave net radiation based on remotely sensed data

International Journal of Digital Earth
Accurate surface shortwave net radiation (SWNR) estimation is crucial for understanding surface energy balance and climate change. However, existing algorithms derive SWNR either indirectly from downward radiation and surface albedo or directly using the

Surface albedo in different land-use and cover types in Amazon forest region

Revista Ambiente & Água, 2018
Albedo is the portion of energy from the Sun that is reflected by the earth's surface, thus being an important variable that controls climate and energy processes on Earth.

Climate changes indicated by trends in snow cover duration and surface albedo in Estonia

Meteorologische Zeitschrift, 1999
Climate changes revealed by trends in snow cover duration and surface albedo over the whole snowy season for Estonian territory are studied. An indirect method is used for deducing surface albedo from snow cover duration.

Ocean surface albedo in AFES

JAMSTEC Report of Research and Development, 2007
The albedo of the ocean surface is of primary importance in the radiative energy balance of the Earth. It takes the smallest value of close to 0 over ocean water and the largest value of nearly 1 over snow-covered sea ice. The albedo of ocean water is determined by of the solar zenith angle, slope of the surface and optical properties of the atmosphere

Dependence of surface albedo on snow cover duration and other snow parameters in Estonia

Meteorologische Zeitschrift, 1995
The duration of snow cover, the state of surface, and the albedo in late winter to early spring are studied as climatic factors. A linear dependence of the surface albedo on the duration of snow cover has been found from the data recorded at Tartu ...

Global glacier albedo changes in the 21st century revealed by MODIS and CMIP6 models

International Journal of Digital Earth
Glacier surface albedo is a crucial variable that controls the energy balance of glacier surfaces, and a decrease in surface albedo can accelerate glacier melting.

Time Series High-Resolution Land Surface Albedo Estimation Based on the Ensemble Kalman Filter Algorithm

Remote Sensing, 2019
Continuous, long-term sequence, land surface albedo data have crucial significance for climate simulations and land surface process research. Sensors such as the Moderate-Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging ...
