Sentences with phrase «earth 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.

(Personally, I believe the sensitivity is on the low side, about 1 to 1.5 °C, simply because this is how Earth reacted in the past to changes in the radiative budget — See JGR - Space, 110, A08105, 2005 [abstract][pdf]-RRB-.

To contribute to an understanding of the underlying causes of these changes we compile various environmental records (and model - based interpretations of some of them) in order to calculate the direct effect of various processes on Earth's radiative budget and, thus, on global annual mean surface temperature over the last 800,000 years.

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.

Reliable data on decadal variability of the Earth's radiation budget are hard to come by, but to provide some reality check I based my setting of the scaling factor between radiative forcing and the SOI / PDOI index on the tropical data of Wielecki et al 2002 (as corrected in response to Trenberth's criticism here.)

Because we understand the energy balance of our Earth, we also know that global warming is caused by greenhouse gases — which have caused the largest imbalance in the radiative energy budget over the last century.

Actually to reach a new, higher equilibrium temperature, the Earth surface (including oceans) must warm and thus the radiative budget MUST be unbalanced, less radiation must be emitted in space compared to the (unchanged) incoming solar radiation.

This surface SW radiative heating is primarily attributed to clouds» — Title: «Global distribution of Earth's surface shortwave budget» Author: N. Hatzianastassiou, et.al.

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.

If the trajectory of both surface and ocean changes following 1998 — then that says there has been a change in the radiative budget of the Earth.

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.»

«It is widely assumed that variations in Earth's radiative energy budget at large time and space scales are small.

Cloud radiative effects are studied in combination with Earth Radiation Budget Experiment fluxes.

The Pacific system resulted in a cloud radiative effect of 1.8 W / m2 over the tropical Pacific — based on Earth Radiation Budget Experiment data.

C climate sensitivity if the observed history of ENSO was included, which was shown from CERES satellite measurements to modulate the Earth's radiative budget naturally (what we called «internal radiative forcing» of the climate system).

SRM techniques are all fundamentally focused on altering the Earth's energy budget, assessed in terms of radiative forcing measured in watts per square meter.

We focus on satellite - and radar - based estimation of various quantities describing the Earth's surface and weather, such as surface albedo, the radiative energy budget, falling and accumulated snow, and cloudiness parameters.

In a sense, what Willis has done is manage to make the same mistake as the people who think that the Earth is in «radiative balance» and try to work out a tedious budget of everything going in and out.

The cloud radiative effect (CRE) on the Earth's present - day radiation budget can be inferred from satellite data by comparing upwelling radiation in cloudy and non-cloudy regions.
