A white area of the retina resulting from edema or infarction.

albedo

the reflectivity of a surface usually expressed as the percentage of radiation reflected e.g. solar radiation reflected from the atmosphere, clouds and the earth's surface. The albedo of an object gives an indication of its composition.

The downloaded MODIS albedo images were in compressed Hierarchical Data Format- Earth Observing System (HDF-EOS) format accompanied by corresponding metadata.
O albedo do solo para radiacao fotossinteticamente ativa ([[alpha].sub.par]) foi estimado pela razao entre a radiacao fotossinteticamente ativa refletida pelo solo abaixo do dossel ([PAR.sub.ref]) e a radiacao fotossinteticamente ativa incidente abaixo do dossel ([PAR.sub.inc]) (FOKEN, 2008).
But black carbon deposits, emitted by burning diesel, wood and fossil fuels, darken the surface of snow and lower its albedo, meaning that it melts faster.
Researchers developed an approach to quantify the impacts of changes to pavement albedo in different locales, and then translate those changes into global warming potential.
where [Q.sub.[alpha][beta]] is the total radiation under the complex terrain (MJ/([m.sup.2] x d)), as is the surface albedo, and [F.sub.[alpha][beta]] is the net surface longwave radiation (NSLR) (MJ/([m.sup.2] x d)).
Experts can use albedo to learn about the composition of a planet's atmosphere, because different ingredients reflect light differently.
The album "The Nutcracker" is Albedo's 12th studio album.
The team was surprised to find that in most cases, the extra energy embodied in the cool material far outweighed the energy savings from increasing the albedo.
found that the local air temperature decreased by 0.6[degrees] C when the pavement-surface albedo increased from 0.05 to 0.30 [16].
Firstly, mature fruits were washed with distilled water and, then, flavedo portion (peel) was separated mechanically, to get the albedo portion (white portion beneath the peel).
The primary objective of this project was to deploy a web-based tool with which users could easily estimate the annual energy cost savings achievable by installing cool roofing products (i.e., those with higher-than-normal albedo, or reflection coefficient) on the most common residential and commercial building types in the United States.
