The characterisation of novel materials presents a challenge that requires new and original developments. To face some of these demands for making measurements at the nanoscale, a new ...

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 ...

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 ...

The Earth's albedo, or reflectance, is a fundamental atmospheric parameter having deep implications for temperature and climate change. For that reason, experiments have been performed to monitor it ...

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 ...

Infrared reflectance spectroscopy is a powerful non-destructive technique for probing the surface and near-surface properties of heterogeneous and layered materials. By measuring the ...

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 ...
