A statistics-based temporal filter algorithm to map spatiotemporally continuous shortwave albedo from MODIS data [PDF]

open access: yesHydrology and Earth System Sciences, 2013
Land-surface albedo plays a critical role in the earth's radiant energy budget studies. Satellite remote sensing provides an effective approach to acquire regional and global albedo observations.

Identifying Spatial and Temporal Characteristics of Land Surface Albedo Using GF-1 WFV Data

open access: yesRemote Sensing, 2021
Land surface albedo (LSA) is an important parameter that affects surface–air interactions and controls the surface radiation energy budget. The spatial and temporal variation characteristics of LSA reflect land surface changes and further influence the ...

New spectral functions of the near-ground albedo derived from aircraft diffraction spectrometer observations [PDF]

open access: yes, 2014
The airborne spectral observations of the upward and downward irradiances are revisited to investigate the dependence of the near-ground albedo as a function of wavelength in the entire solar spectrum for different surfaces (sand, water, snow) and under ...

Reconstruction of Historical Land Surface Albedo Changes in China From 850 to 2015 Using Land Use Harmonization Data and Albedo Look‐Up Maps

open access: yesEarth and Space Science, 2021
Land surface albedo is a critical parameter of the Earth's energy budget and has been greatly altered by climate change and human activities. To improve our understanding of historical land surface albedo changes and their climatic effects before the ...

Development of a high spectral resolution surface albedo product for the ARM Southern Great Plains central facility [PDF]

open access: yesAtmospheric Measurement Techniques, 2011
We present a method for identifying dominant surface type and estimating high spectral resolution surface albedo at the Atmospheric Radiation Measurement (ARM) facility at the Southern Great Plains (SGP) site in Oklahoma for use in radiative transfer ...

Can uncertainties in sea ice albedo reconcile patterns of data-model discord for the Pliocene and 20th/21st centuries? [PDF]

open access: yes, 2014
General Circulation Model simulations of the mid-Pliocene warm period (mPWP, 3.264 to 3.025 Myr ago) currently underestimate the level of warming that proxy data suggest existed at high latitudes, with discrepancies of up to 11°C for sea surface ...

Albedo over rough snow and ice surfaces [PDF]

open access: yesThe Cryosphere, 2014
Both satellite and ground-based broadband albedo measurements over rough and complex terrain show several limitations concerning feasibility and representativeness.

Spatial Heterogeneity and Temporal Variation in Urban Surface Albedo Detected by High-Resolution Satellite Data

open access: yesRemote Sensing, 2022
Albedo is one of the key parameters in the surface energy balance and it has been altered due to urban expansion, which has significant impacts on local and regional climate.

A Note on the Albedo of Surfaces [PDF]

open access: yesJournal of Applied Meteorology, 1972
Abstract The albedo of a variety of surfaces was measured for a total of approximately 400 hr with Middleton solari-albedometers whose outputs were recorded by a computer-controlled data acquisition system. The albedo for each surface was expressed as a function of solar zenith angle, with strong relationships between the two being obtained for most ...

Variation in Albedo and Its Relationship With Surface Dust at Urumqi Glacier No. 1 in Tien Shan, China

open access: yesFrontiers in Earth Science, 2020
Surface albedo is an important driver of surface processes that promote glacier melting and is a key variable influencing glacier surface melt. Despite much focus in the literature on variations in albedo and its influence on snow surfaces, little ...
