When the spacecraft succumbs to the atmosphere, breaking up and unable transmit any more data, it will burn up like a meteor in Saturn's upper atmosphere, NASA officials said.

C. Carreau, ASPERA - 4 & MAG teams, Venus Express, ESA Annotated image illustrating loss of hydrogen through plasma wake Venus may have lost oceans of water due to a runaway greenhouse effect which evaporated water into the upper atmosphere, where ultraviolet light dissociated water into ionized atomic hydrogen and oxygen (some later incorporated into carbon dioxide) that were blown away by the Solar wind due to the lack of a strong magnetic field like the Earth's (more).

Our next step will be to look for other features in the upper atmosphere, as well as investigating the Great Cold Spot itself in more detail.»

The best possible observations of the detached layer are made in ultraviolet light because the small haze particles which populate this part of Titan's upper atmosphere scatter short wavelengths more efficiently than longer visible or infrared wavelengths.

On its current trajectory, Cassini has also taken the first - ever in - situ samples of Saturn's atmosphere, and Linda Spilker, the Cassini project scientist, said those early results suggest that the chemical and dynamic interactions between particles from the planet's rings and the planet's upper atmosphere are «more complex... than we had both anticipated.»

of anthropogenic CO2 releases that have been taken out of the atmosphere (over and above the amount taken out of the atmosphere that balances the natural additions to the atmosphere), perhaps mainly as a direct biogeochemical feedback (increased CO2 favoring more rapid biological fixation of C, net flux of CO2 into water until equilibrium for the given storage of other involved chemical species in the upper ocean) fairly promptly.

Less TOA cooling will occur if bands are placed where, in the upper atmosphere or near TOA, they absorb more of the increases in radiation from below from surface + tropospheric (+ lower stratospheric) warming.

Adding more optical thickness to the same band reduces OLR in that band, cooling at least some portion of the upper atmosphere up to the TOA level, and increases in OLR outside that band results in some portion of that cooling remaining at full equilibrium (as expained by Andy Lacis).

Add in that if it's the sun, the entire atmosphere will warm, since there's just simply more energy put in to the system, whereas if it is CO2 or other blanketing method, there's no extra energy put in, therefore the ground will warm and the upper air cool (since the upper air isn't getting the warming from the lower layers it used to get and the lower layers aren't losing the heat they used to).

Yes, but the upper part of the atmosphere will remain thin by virtue of the fact that if you add more gas, the TOA goes to a higher altitude.

Demand is not as sexy as giant wind turbine platforms being towed out to sea or strung up on steel kites into the upper atmosphere, but demand side effciences are faster, less costly, and more effective.

For the upper - atmosphere cooling, I simply remark that infrared coming up from below is blocked more, as more greenhouse gases are added, so of course it's cooler above the blocking.

As more optical thickness is added to a «new» band, it will gain greater control over the temperature profile, but eventually, the equilibrium for that band will shift towards a cold enough upper atmosphere and warm enough lower atmosphere and surface, such that farther increases will cool the upper atmosphere or just that portion near TOA while warming the lower atmosphere and surface — until the optical thickness is so large (relative to other bands) that the band loses influence (except at TOA) and has little farther effect (except at TOA).

The upper layers of the earth's oceans are a lead suspect for absorbing more heat that otherwise would remain in the atmosphere.

For instance, back in the 1960s, simple climate models predicted that global warming caused by more carbon dioxide would lead to cooling in the upper atmosphere (because the heat is getting trapped at the surface).

The NCAR scientists now state these satellites still see there is more energy radiation entering the upper atmosphere than leaving it, in whatever part of the spectrum.

The ITCZ lies at the foot of the ascending branch of the Hadley circulation, and the circulation transports energy in the direction of its upper branch, because energy (or, more precisely, moist static energy) usually increases with height in the atmosphere.

Note that this argument applies to all levels of the atmosphere, including the upper levels where carbon dioxide is relatively less abundant, and that the line of reasoning also becomes more potent (in the sense that less additional warming is forced) the more carbon dioxide that either humans or nature emit.

All that the gravito - thermal GHE does is redistribute the heat from the only energy SOURCE the Sun, more to the surface (the 33K G - T) and less to the upper troposphere (the even larger NEGATIVE -LRB--35 C) ANTI-GREENHOUSE EFFECT) from the center of mass of the atmosphere at 5.1 km to the top of the troposphere.

During a cooling phase, surface atmosphere could cool as heat is transported to upper atmosphere by more intense weather and then radiates away.
