Sentences with phrase «surface reflectivity»
Surface reflectivity refers to the amount of light that is bounced back or reflected off a surface. It describes how much the surface reflects light rather than absorbing it. A surface with high reflectivity will appear shiny or shiny, as it reflects a lot of light, while a surface with low reflectivity will appear dull or dark, as it absorbs more light. Full definition
An invested concentration in surface reflectivity as its own medium is present in much of Hodges» work — glass, gold and polished stainless steel — and allows for multiple readings, broadening experiential possibilities and disrupting notions of a fixed site.

But by estimating surface reflectivities and using its distances from the Earth and Sun at the time of the HST observations, we can determine the range of plausible sizes it might have.
Assuming surface reflectivities ranging from 4 % (like the darkest known KBOs), to 15 % (like many KBOs), to 35 % (like Charon), this is what we find:
S / 2005 P 2 is about 25 % fainter than S / 2005 P 1, so could be a 10 % to 15 % smaller than S / 2005 P 1, assuming they have the same surface reflectivity.
Because of the great deal of energy needed to remove mass by sublimation, the ablation rate will be very insensitive to changes in conditions — whether air temperature or precipitation - determined surface reflectivity — in circumstances where all ablation is due to sublimation.
Furthermore, land vegetation has a significant effect on surface reflectivity, heat, moisture, and energy.
But these snow - covered caps are increasingly interrupted by pits like these, whose black mud bottoms of rocky sediment called cryoconite drastically reduces polar surface reflectivity.
A similar paper by many of the same authors recently published in the Proceedings of the National Academy of Science (Clark et al. 2012) estimates the greenhouse gas radiative forcing during the transition at approximately 2.5 Watts per square meter (W / m2), but neither Shakun nor Clark et al. estimated the total radiative forcing (including surface reflectivity changes, for example).
Far more certainly there will be changes in surface reflectivity; changes in snow and ice cover, open water area, regions of desert, vegetation patterns etc..
«MAX Reflective offers 100 - percent surface reflectivity and is incredibly durable, unlike other solutions that use reflective strips or printing that can wear off.»
«That back layer is very critical to get thinner wafers [of silicon] and better back surface reflectivity and, thus, lower cost and higher efficiency.»
By measuring the surface temperature of a Kuiper Belt object, and combining this with optical observations, its surface reflectivity and hence its diameter can be determined accurately.
It confirmed that the mean albedo, or surface reflectivity, of the Arctic ice zone in late summer declined over an almost three - decade period, between 1982 and 2009.
New «benchmark» for loss of reflectivity Another wild card is the loss of the albedo of the ice, or its surface reflectivity.
Despite the various uncertainties in what we know about P1 and P2 so far, and regardless of their surface reflectivities, these bodies are clearly very small compared to both Pluto (2284 km diameter) and Charon (1192 km diameter).
Because we do not yet know its surface reflectivity, we can not definitively calculate its exact size.
We know their brightnesses, but not their rotation periods, their colors, their surface reflectivities, or their surface compositions.
every grid box has a change in radiation if there is a change in GHG or aerosol composition; ozone changes affect the stratosphere and troposphere directly; land - use changes affect the surface reflectivity and water cycling etc. — gavin]
Deforestation was allegedly increasing Earth's surface reflectivity, causing sunlight to bounce back into space without heating the surface — and smokestack particulate emissions were blocking out light before it got here.
The «buying time» argument — according to which we can temporarily increase the Earth's albedo (surface reflectivity) while the world decides to put CO2 controls in place — has fallen out of favour because any warming suppressed by a solar shield will just come back to bite us once the shield is removed.
New research shows algae growing on the Greenland ice sheet, the Earth's second - largest ice sheet, significantly reduce the surface reflectivity of the ice sheet's bare ice area and contribute more to its melting than dust or black carbon.
New research shows algae growing on the Greenland ice sheet significantly reduce the ice sheet's surface reflectivity and contribute more to its melting than dust or black carbon.
Forcing agents vary such as surface reflectivity, greenhouse gases and natural variation in atmospheric and ocean cycles as well as longer term forcing agents such as the Milankovitch cycles that drive long term climate change.
Other potential causes of climate change include the depletion of stratospheric ozone in recent decades, again through human activities, and global changes in the surface reflectivity — or albedo — of the planet, as we modify the patterns of vegetation that cover the land.
• The reduction of sea ice causes the surface reflectivity to strongly decrease in the Arctic, which leads to decreases in shortwave radiation in the atmosphere and, thus, lower photo - dissociation rates of tropospheric gases.
