To help improve the accuracy of climate models, an international team involving the National Physical Laboratory (NPL) has measured the reflectance of rough, snow-covered surfaces at large solar ...

The amount of sunlight that Earth reflects back into space — measured by the dim glow seen on the dark portions of a crescent moon’s face — has decreased measurably in recent years. Whether the ...

In spectroscopic analysis, the development of cost-effective handheld infrared spectrometers has revolutionized monitoring ...

The way leaves reflect light, known as plant reflectance spectra, can illuminate the evolutionary history of seed plants, according to researchers. The researchers found that by measuring the light ...

Southwest Research Institute (SwRI) scientists are collaborating with researchers at UT San Antonio to study how space weathering can alter the lunar surface materials to help interpret regional and ...

An image printed on reflectance paper responds to the direction from which it is illuminated. The reflectance paper is covered with dimples that reflect light from different directions. See video ...
