A review of snow and ice albedo and the development of a new physically based broadband albedo parameterization
[1] We present a computationally simple, theoretically based parameterization for the broadband albedo of snow and ice that can accurately reproduce the theoretical broadband albedo under a wide range of snow, ice, and atmospheric conditions. Depending on its application, this parameterization requires between one and five input parameters. These parameters are specific surface area of snow/ice...
متن کاملA parameterization of ocean surface albedo
[1] 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 in terms of these four important paramet...

متن کاملThe Effects of Continental-Scale Snow Albedo
The NCAR CAM3 GCM with prescribed, satellite-based snow 3 albedo (SA) is used to investigate the remote effects of snow cover on North-4 ern Hemisphere (NH) winter climate. A pair of 100 ensemble member ex-5 periments are integrated through the autumn-winter season, with prescribed 6 high and low SA over Eurasia (EA). Similar to other non-CAM GCM stud-7 ies using prescribed snow mass, anomalous...
متن کاملBlack-carbon reduction of snow albedo
Climate models indicate that the reduction of surface albedo caused by black-carbon contamination of snow contributes to global warming and near-worldwide melting of ice1,2. In this study, we generated and characterized pure and black-carbonladen snow in the laboratory and verified that black-carbon contamination appreciably reduces snow albedo at levels that have been found in natural settings...
