so high that monsoon air then ascends freely into the stratosphere, the stable layer that overlies the
lower part of the atmosphere and contains the Earth's protective ozone layer.
With higher precipitation, portions of this snow may not melt during the summer and
so glacial ice can form at
lower altitudes and more southerly latitudes, reducing the temperatures over land by increased albedo as noted above.

lower stratosphere is pretty efficient in comparison to the time it takes to remove CO2 at the surface,

low drag at high
altitudes to go faster, but a naturally aspirated engine does not produce enough power at the same
altitude to do
so.
However, Quito is located at over 9,000 feet,
so altitude can be a problem for travelers arriving from
lower elevations.

lower elevation now (at about 9,000 feet)
so the effects of the
altitude are less here.

altitude on the Inca Jungle trek is generally
lower than that of Cuzco (3,400 m),
so after a few days acclimatising there you should be fine.
If one experiences any
altitude sickness in Cusco they will want to tell the private guide for the day
so he may revise the itinerary to visit a small town in a
lower altitude.
Vigorous convective mixing in the deep tropics also dilutes changes in near - surface CO2 much more than at higher latitudes,
so low -
altitude sampling contains relatively less information about carbon sources and sinks.
Multiplied by the decreasing density with
altitude (the other half), there is always just enough pressure for the
lower layers of the atmosphere to hold up the upper layers and
so on up leading to
lower and
lower pressure with
altitude as there is less and less mass above each layer (hydrostatic equilibrium).
Paradoxically temperatures in the middle troposphere (400 mb) have been falling, perhaps reflecting a combination of effects, like surface warming, drier middle
altitudes,
lower solar influence and
so on?
I understand how things like changing the paint to something more reflective could result in a cooling step change, or moving from less windy to more windy location could add evaporative cooling, and going from a
lower to higher
altitude, or moving into a seabreeze, and
so forth.
To do
so, you'd need a study such as mine which shows water vapour cools and more moist regions have
lower mean daily maximum and minimum temperatures than drier regions at similar latitudes and
altitudes.
More light is absorbed at higher
altitudes compared to the
lower stratosphere,
so the temperature increases.
The last cycle was weaker (and

Tim Folkerts says: >>
So the heavy gases are enriched at
low altitudes, but do not completely >> displace the lighter molecules.
However, it is much easier to figure out what happens when you add more radiative gases to an atmosphere that already has them: And, the answer is that it increases the IR opacity of the atmosphere, which increases the
altitude of the effective radiating level and hence means the emission is occurring from a
lower - temperature layer, leading to a reduction of emission that is eventually remedied by the atmosphere heating up
so that radiative balance at the top - of - the - atmosphere is restored.
