On a global scale, the heating
of atmospheric molecules causes the lower atmosphere, or troposphere, to expand and stretch higher during the day; it then settles back down as it cools at night.
Tinetti says the earlier studies could be a product of the planets» bright sides cooking to the same temperature throughout, which
makes atmospheric molecules less likely to absorb radiation from below.
As a planet transits its star, the starlight passes through the planet's atmosphere,
where atmospheric molecules, for example ozone or carbon dioxide, absorb some of the starlight.
And energy out mostly by radiation, however, as much as 20 % of escaping energy is simply highly
energized atmospheric molecules; which furthers vertical convection all the way out to the inside of Earth's magnetic bottle, and the Van Allen radiation belt.
While Jupiter - class planets may be much less massive than brown dwarfs, they are about the same diameter and may contain many of the
same atmospheric molecules.
The radiative absorption capability of CO2
allows atmospheric molecules to reach a higher temperature than that imparted to them by energy at the surface so they rise to a higher location than would be predicted from their weight and their individual gas constants.
Now if the entire process were instant there would be no problem but it all takes time for air to rise and then fall so the process is out of phase with the normal radiative flow of solar shortwave in and longwave out and has been since the very
first atmospheric molecules floated above the surface.
Radiation at ultraviolet wavelengths
dissociates atmospheric molecules, initiating chains of chemical reactions — specifically those producing stratospheric ozone — and providing the major source of heating for the middle atmosphere, while radiation at visible and near - infrared wavelengths mainly reaches and warms the lower atmosphere and the Earth's surface1.
The heat of the daylight could have cooked the atmosphere evenly all the way down, Barman says, which reduces absorption of light
by atmospheric molecules.
At the present time, the concentration is about 390 ppm, 0.039 percent of
all atmospheric molecules and less than 1 percent of that in our breath.
Previously, UV light from the sun was thought to heat up
atmospheric molecules, exciting them enough that they jump off into space.
In theory, the interaction between the solar wind's energetic particles and
atmospheric molecules could explain the GRaND observations.
Near Titan's surface, about 5 percent of
the atmospheric molecules are methane, the fraction decreasing with altitude.
The higher the force of attraction between the moon and
an atmospheric molecule, the longer the molecule is retained.
«But once
the atmospheric molecules are ionized, they see the interplanetary (solar) magnetic field and are «picked up» by electric forces and carried away by the solar wind.
How long does a CO2 molecule at 5.5 kms height hold on to that absorbed IR photon before it is released (emitted or transferred though collision to
another atmospheric molecule)?
When
an atmospheric molecule absorbs radiant energy it vibrates faster thereby becoming warmer.
When
an atmospheric molecule absorbs energy by conduction or radiation it vibrates faster thereby becoming warmer.
The light is scattered by
the atmospheric molecules and particles, and a fraction is collected back on the ground with a telescope.
Yes, it is way up in the atmosphere; but still it is only 37 of every 100,000
atmospheric molecules.
Your comment seems to rest upon the strange and magical concept that
each atmospheric molecule of a low - specific - heat gas (such as argon) lives in its own little parallel universe and does not interact (collide) with neighbouring molecules of other types.
For example — at what height would 90 % of
the atmospheric molecules be below you?
