Sentences with phrase «toa radiation changes»

Large - scale TOA radiation changes during the past decade are observed to be within 0.5 Wm ^ 2 per decade based upon comparisons between Clouds and the Earth's Radiant Energy System (CERES) instruments aboard Terra and Aqua and other instruments...

Thus if the sun were to become stronger by about 2 %, the TOA radiation balance would change by 0.02 * 1366 * 0.7 / 4 = 4.8 W / m2 (taking albedo and geometry into account) and this would be the radiative forcing (RF).

How do you explain the measured changes in the radiation profile TOA that are in accordance to predictions based on Greenhouse gas theory?

Lessons from simple toy models and experience with more sophisticated GCMs suggests that any perturbation to the TOA radiation budget from whatever source is a pretty good predictor of eventual surface temperature change.

The effect where, adding a «new» absorption band and increasing the absorption, there may initially be warming of the colder layers, etc, followed by a stage of upper level or near - TOA cooling — this includes the warming from absorption from increased radiation from the surface + troposphere — which will be greater when more of the spectrum, especially near wavelengths where the emitted spectral flux change is greatest, has a greater amount of absorption.

First, for changing just CO2 forcing (or CH4, etc, or for a non-GHE forcing, such as a change in incident solar radiation, volcanic aerosols, etc.), there will be other GHE radiative «forcings» (feedbacks, though in the context of measuring their radiative effect, they can be described as having radiative forcings of x W / m2 per change in surface T), such as water vapor feedback, LW cloud feedback, and also, because GHE depends on the vertical temperature distribution, the lapse rate feedback (this generally refers to the tropospheric lapse rate, though changes in the position of the tropopause and changes in the stratospheric temperature could also be considered lapse - rate feedbacks for forcing at TOA; forcing at the tropopause with stratospheric adjustment takes some of that into account; sensitivity to forcing at the tropopause with stratospheric adjustment will generally be different from sensitivity to forcing without stratospheric adjustment and both will generally be different from forcing at TOA before stratospheric adjustment; forcing at TOA after stratospehric adjustment is identical to forcing at the tropopause after stratospheric adjustment).

To me, it is more likely the fluctuation in E-UV coming from the sun that causes the warming and cooling effects by changing the reactions that are happening on TOA, i.e. O3, HxOx and NOx are rising now, causing more back radiation of F - UV, meaning less energy going in the oceans.

On going up expansion work PdV is stored by the surroundings (temperature dropping by 9.8 K / km) At TOA there will be a loss of heat by radiation to space causing the down phase On going down the surroundings do work on the parcel (PdV)(temperature increasing by 9.8 K / km) Stationary parcels will not change temperature.

So, which models are we talking about, and what values do they show when it comes to hindcasting and forecasting OHC, TOA net SW radiation, TOA net LW radiation and changing lapse rate?

«Our results demonstrate how synergistic use of satellite TOA radiation observations and recently improved ocean heat content measurements, with appropriate error estimates, provide critical data for quantifying short - term and longer - term changes in the Earth's net TOA radiation imbalance.

I suspect that the Atlantic sequestration impact is amplified by atmospheric circulation changes that change the cloud distribution that change both the TOA and surface radiation balances.

Cloud cover changes are significant determinants of the Earth's top - of - atmosphere (TOA) radiation imbalance, or how much solar radiative forcing is absorbed by the Earth's surface (oceans).

This new paradigm states that rather than the TOA (top of the atmosphere) energy balance being maintained by changes to the outgoing long wave radiation (which is saturated), it is mainly maintained by changes to the outgoing short wave radiation, i.e. albedo.
