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 ...

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

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

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 ...

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

International 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

Observation of Albedo at the Surface of Pavement

Journal of the Japanese Society of Snow and Ice, 1973
Albedo of the surface of pavement is closely related to behavior of the surface temperature of pavement. Therefore, it is an effective factor for a theoretical analysis of the surface temperature. The observation of albedo was made at the surface of a dense grade asphalt concrete pavement in Ebetsu-shi, Hokkaido during the period from November 5 to ...

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

The 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

Changing Regional Land Surface Albedos Alter the Planetary Albedo During the Twenty‐First Century

Earth's Future
The top‐of‐atmosphere (TOA) albedo controls the amount of solar energy absorbed by Earth and is influenced by the reflectivity of both the atmosphere and surface.

Competing effects of surface albedo and orographic elevated heating on regional climate

Geophysical Research Letters, 2017
All else being equal, a given atmospheric pressure level is thought to be warmer over a plateau than over surrounding nonelevated terrain because of orographic “elevated heating.” However, elevated surfaces are also typically brighter due to reduced ...

Improving Urban Climate Adaptation Modeling in the Community Earth System Model (CESM) Through Transient Urban Surface Albedo Representation

Journal of Advances in Modeling Earth Systems
Increasing the albedo of urban surfaces, through strategies like white roof installations, has emerged as a promising approach for urban climate adaptation.
