What I'm saying is that TOA, as far as radiative energy is concerned, for CO2 or other IR absorbing gas, is effectively the altitude where the chance that a photon will be absorbed, and emitted back in a direction that will lead it to being absorbed again by a molecule in the atmosphere, becomes negligible.

Machu Picchu is not at an altitude where altitude sickness typically occurs, but visitors are likely to stay at risk altitudes before visiting the archaeological site.

The three drag races between the two cars end with the Stingray on top each time, though just barely, but the video host points out that the test was done at high altitude where the air has less oxygen, putting the oxygen - loving Corvette V8 at about a 15 percent power disadvantage but having no effect on the electric motor of the i8.

You exhale and perspire more at high altitude where the air humidity is lower, causing you to lose up to a quart more of water per day than you normally would.

Although no one is sure what triggers their formation, one theory is that cosmic dust, or debris from burned - up meteors, seed the ice particles, which is plausible because meteors typically are incinerated in the upper mesosphere at about the same altitude where these clouds form.

At some airports — especially those with long runways in temperate regions and at low altitude where the air is relatively dense, like New York City's John F. Kennedy, London's Heathrow, and Paris's Charles de Gaulle airports — impacts should be minimal, the researchers report today in Climatic Change.
