A coarse resolution coupled ocean-atmosphere simulation where surface albedo feedback is artificially suppressed by prescribing surface albedo is compared to one where snow and sea ice anomalies are allowed to affect surface albedo, as the model was originally designed. Canonical CO -doubling experiments were performed with both models to assess the impact of surface albedo feedback on equilibr...

The surface albedo of the Arctic sea ice zone is a crucial component in the energy budget of the Arctic region [1, 2]. The treatment of sea ice albedo has been identified as a main source of variability in the future sea ice mass loss forecasts in coupled climate models [3]. There is a clear need to establish datasets of Arctic sea ice albedo to study the changes based on observational data, an...

The land surface albedo is among the most important parameters controlling the atmospheric radiation fluxes and the surface–atmosphere interactions. In the present study, surface albedo parameters and aerosol optical thickness (AOT) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor, onboard NASA’s Terra and Aqua satellites, were analyzed and processed for the estimation...

Snow albedo feedback is one of the most crucial feedback processes that control equilibrium climate sensitivity, which is a central parameter for better prediction of future climate change. However, persistent large discrepancies and uncertainties are found in snow albedo feedback estimations. Remotely sensed snow cover products, atmospheric reanalysis data and radiative kernel data are used in...

Citrus oil is a clear volatile oil with a pleasant pungent odor. The material furnished for these experiments was extracted from citrus peel and is double distilled. Citrus peel oil mixed with dehydrated gum turpentine in the proportions of 80 per cent and 20 per cent respectively, has been used commercially as a deodorant and an insect repellant. Because of its penetrating properties citrus oi...

In recent years, high-albedo materials and products have been utilized for urban building roofs and roads to lower their surface temperatures. These high-albedo materials and products include those with spectral selectivity. Accordingly, a numerical simulation was conducted to investigate the spectral dependency and characteristics of the urban albedo. The distribution of the spectral albedo re...

Optical satellite albedo observations of forests suffer from understory contamination, but C-band microwave reacts mostly with the canopy. This paper studies whether or not adding ASAR backscattering information could enhance optical albedo retrieval accuracy. We compare SPOT-4-retrieved reflectances combined with ASAR backscattering ratios with solely optically retrieved SPOT-4 NIR albedo, and...
