Sentences with phrase «outgoing radiation»
The phrase "outgoing radiation" refers to the energy that is emitted or sent out from the Earth and its atmosphere as heat or light. It is the opposite of incoming radiation, which is the energy that comes from the Sun to the Earth. Outgoing radiation helps regulate the Earth's temperature and plays a key role in the Earth's climate system. Full definition
This conveniently means there is no distortion to the amount of outgoing radiation from the top of the atmosphere which would only upset the balance of radiation in and out.

With an added forcing, temperature increases which increases outgoing radiation until the radiation budget is back in balance.
The incoming and outgoing radiation doesn't even know the other exists, it can't see it, it can't feel it, they have absolutely no effect on one another.
In either case the temperature is independent of the details of the temperature structure below, the key point is that the total outgoing radiation must balance the incoming solar radiation.
A planet's outgoing radiation comes from this upper layer.
The radiative forcing due to a change in concentration of CO2 is the change in balance between incoming and outgoing radiation caused by the change in CO2 concentration.
When there are no greenhouse gases the atmosphere can not absorb incoming radiation or emit outgoing radiation.
Rather, attempts are made to estimate the differences and trends over time between incoming and outgoing radiation so as to calculate an energy imbalance at the top of the atmosphere.
It has to keep supplying the kinetic energy required to maintain atmospheric height and it has to still be warm enough to match outgoing radiation with incoming radiation from an external source.
Also striking is the huge difference in outgoing radiation between the north and south polar regions.
The answer is yes, it slightly raises the location of outgoing radiation to space, and thus the lapse rate times the slight increase in altitude would raise the ground temperature.
So, the net effect is an increase in outgoing radiation.
At the top, the total incoming radiation is equal to the total outgoing radiation.
Lindzen and Choi (2009), slightly revised as Lindzen & Choi (2011), used measurements of sea surface temperature in the tropics and satellite measurements of outgoing radiation from 2000 to 2010 in an attempt to determine climate sensitivity, ultimately concluding that sensitivity is less than 1 °C for doubled atmospheric CO2.
My own prediction is that, as temperatures fail to increase over the next five years, attention will turn to Ray Ladbury's «bite» — the resonant absorption of outgoing radiation by CO2 and H2O in the radiation spectrum viewed from space.
What happens at the «top of atmosphere» — the level where outgoing radiation leaves for space, not itself a very easy concept — is the restoration of equilibrium, the increase in temperature that, through Helmholtz - Boltzmann at the Earth's brightness temperature 255K, restores the balance between incoming and outgoing energies.
I get that incoming and outgoing radiation energy must balance and that radiation is the only way the Earth could come to equilibrium with the Sun and space.
In contrast to this, the calculated TOA outgoing radiation fluxes from 11 atmospheric models forced by the observed SST are less than the zero feedback response, consistent with the positive feedbacks that characterize these models.
Absolute values of the difference for realistic cases are less than 0.05 W / m ^ 2 / K, which is not significant for climate studies that employ regressions of outgoing radiation against temperature.
Increasing GHG concentrations slows outgoing radiation.
A recent paper by Lindzen and Choi in GRL (2009)(LC09) purported to demonstrate that climate had a strong negative feedback and that climate models are quite wrong in their relationships between changes in surface temperature and corresponding changes in outgoing radiation escaping to space.
Px272 Lect 3: Forcing and feedback Balance of solar incoming, and earth emitted outgoing radiation Increments.
Lacis points out that only outgoing radiation can balance the global energy budget of the Earth; as clearly the convection and conduction ends at the boundary of the atmosphere.
iii) The failure of outgoing longwave radiation (OLR) to show that there was any increased atmospheric blocking of outgoing radiation following short term troposphere warming episodes.
Therefore in a situation where the incoming radiation is greater than the outgoing, this must be a symptom of a change in the system (i.e. outgoing radiation is being converted to heat) and isn't the mechanism that actually instigates the change.
The frequencies at which outgoing radiation originate have not changed that much - it's mostly the height of the atmosphere from which they are radiated that changes.
