Sentences with phrase «high albedo»
"High albedo" refers to a surface that reflects a lot of sunlight, rather than absorbing it. This means it appears bright and doesn't get as hot when exposed to the sun as surfaces with lower albedo. Full definition
Replacement of forests with shorter vegetation together with the normally assumed higher albedo could then cool the surface.

More clouds means higher albedo, which in turn might mean a cooler climate.
Clouds with highest albedo have large droplets.
The famous «255 K» value for no greenhouse effect on Earth is an example of this, although in reality if we got that cold you would expect a snowball - like Earth and a much higher albedo from the increased brightness of the surface... and thus the «no - greenhouse temperature» would be even colder than 255 K.
But the theory is based on misconceptions and you can easily prove it's wrong by looking at rain clouds, dark underneath so higher albedo yet have larger droplet size.
«Ice911: Developing an Effective Response to Climate Change in Earth's Cryosphere using High Albedo Materials,» Leslie A Field, Peter Wadhams, Terry Root, Satish Chetty, Daniel M Kammen, Shalini Venkatesh, Dolf van der Heide, and Ellen Baum, American Geophysical Union Fall Meeting, San Francisco, CA, December 2012.
Albedo is a measure of how reflective a surface is, wither higher albedo being more reflective.
The central business districts of some urban areas can therefore have quite high albedo rates (proportion of light reflected);
However, Venus's higher albedo of 0.76 reflects a greater fraction of sunlight, greatly reducing the average absorbed flux to
The roof is a high albedo system (white roof) which reduces cooling load.
Cement concrete is lighter in color and has a higher albedo.
Is this because of the high albedo of the Antarctic ice cap?
In her global maps of Europa, Callisto and Ganymede, the color gradient represents the surface temperature — blue means colder and therefore, presumably a more reflectively surface (higher albedo).
That means it has a high albedo.
The higher albedo around the margins of the ice sheet, where summer melt is highest, shows the impact of summer snows in muting that melt.
However, I had to wear my white dress, because it's perfect for being outside in the heat (white increases your albedo, and a higher albedo means more sunlight reflected off of you, so you don't feel as warm!).
Thick clouds about to rain are not the same as thick (fluffy, high albedo) clouds with lots of pollution caused CCN.
Kjell Arne Rekaa @ 72, although Venus is closer to the sun it has a much higher albedo than Earth, so it reflects more incoming solar energy back out to space before it can be absorbed.
Carbon sequestration would increase; a thickening soil layer and higher albedo would provide better insulation than what now exists.
