Sentences with phrase «atmosphere radiative budget»

Not exact matches

Using global climate models and NASA satellite observations of Earth's energy budget from the last 15 years, the study finds that a warming Earth is able to restore its temperature equilibrium through complex and seemingly paradoxical changes in the atmosphere and the way radiative heat is transported.

Similarly, many studies that attempt to examine the co-variability between Earth's energy budget and temperature (such as in many of the pieces here at RC concerning the Spencer and Lindzen literature) are only as good as the assumptions made about base state of the atmosphere relative to which changes are measured, the «forcing» that is supposedly driving the changes (which are often just things like ENSO, and are irrelevant to radiative - induced changes that will be important for the future), and are limited by short and discontinuous data records.

Surface radiative energy budget plays an important role in the Arctic, which is covered by snow and ice: when the balance is positive, more solar radiation from the Sun and the Earth's atmosphere arrives on the Earth's surface than is emitted from it.

The troposphere is currently cooling radiatively at about 2K / day, and adding CO2 to the atmosphere generally increases the radiative cooling (primarily through increases in water vapor, though how these details play out also depend on the details of the surface budget).

wilt, the paper you cite describes what in their view is a «small but statistically significant effect of cosmic rays on cloud formation, which in no way invalidates the large and significant effects of human emissions on the current anthropogenic radiative forcing budget of the atmosphere.

Terrestrial, solar radiation propagation in the atmosphere; radiative components in energy budgets, weather systems, climate studies; remote sensing

But on larger scales (both in space and time) the earth is a planet of our local star; the sun is our only source of (purely radiative) energy; we have an atmosphere which clearly operates to reduce diurnal variations in temperature (which on black body basis would otherwise be huge, on human scale) and the radiative budget must always be exactly in balance.

Patrick Brown and Ken Caldeira of the Carnegie Institution for Science say incorporating observational data of «Earth's top - of - atmosphere energy budget» shows the «warming projection for the end of the twenty - first century for the steepest radiative forcing scenario is about 15 per cent warmer (+0.5 degrees Celsius)... relative to the raw model projections reported by the Intergovernmental Panel on Climate Change.»

We present new evidence from a compilation of over two decades of accurate satellite data that the top - of - atmosphere (TOA) tropical radiative energy budget is much more dynamic and variable than previously thought.

Clouds are, in fact, probably the dominant influence in the radiative budget of the lower atmosphere but adequately taking them into account raises many problems -LSB--RSB- The Physics of Atmospheres, p. 41.

The Greenland ice sheet plays a crucial role in the Arctic and global climate systems through its impact and feedbacks on radiative budget, ocean, atmosphere and ecosystems.

A lot of confusion seems to lie in not realizing that all the energy entering and leaving at the TOA is radiative, and as a result of this the effect of the non radiative fluxes from the surface (from latent heat of water and thermals) on the radiative budget has to be zero, because COE dictates that the atmosphere can not create any energy of its own.

Assuming 1 % hydrate by pore water volume were released on average from the slide volume, you get a methane release of about 0.8 Gton of C. Even if all of the hydrate made it to the atmosphere, it would have had a smaller climate impact than a volcanic eruption (I calculated the methane impact on the radiative budget here).
