Sentences with phrase «snow grain size»

The relatively large temperature response is related to positive feedbacks which enhance the initial impact of changed snow grain size.

MODIS - based Mosaic of Antarctica (MOA) data sets: Continent - wide surface morphology and snow grain size.

The relatively large temperature response is related to positive feedbacks which enhance the initial impact of changed snow grain size.

But Dumont and her colleagues have found that, since 2009, there has been a darkening that can not be explained by larger snow grain size alone.

Not exact matches

Two properties dominate reflectivity in dry snow — the size of snow grains, which become larger and more absorbent as they melt, and the presence of dark impurities that absorb the sun's energy, predominantly black carbon and mineral dust, which also cause the snow to melt faster.

Nakamura, T., Abe, O., Hasegawa, T., Tamura, R., Ohta, T. (2001) Spectral reflectance of snow with a known grain - size distribution in successive metamorphism.

This is, however, a complex process: the reflection by snow results from scattering of sunlight by numerous snow grains with largely varying shapes and sizes.

Freshly fallen snow reflects up to 84 percent of incoming sunlight, but during the warm season the reflectivity declines as the ice grains within the snowpack change shape and size.

Smaller - sized graupels are generally referred to as snow grains.

The snow albedo depends not only on snow grain shapes but also their sizes and other factors like impurities in snow.

This is, however, a complex process: the reflection by snow results from scattering of sunlight by numerous snow grains with largely varying shapes and sizes.
