It's sort of hard to define exactly where the atmosphere ends and outer space begins (since the atmosphere gradually falls off
as you go up in
altitude), but one popular choice is the so - called «Karman line» at a height of 100
km (or around 62 miles) above sea level.
Albert VI, also known
as Yorick, survived his 1951 flight, though it topped out at an
altitude of just 45 miles (72
km)-- significantly below the generally accepted 62 - mile (100

km.
«We have flown radiation sensors onboard 264 research flights at
altitudes as high

km (56,700 ft) from 2013 to 2017,» says Kent Tobiska, lead author of the paper and PI of the NASA - supported program Automated Radiation Measurements for Aerospace Safety (ARMAS).
Although the difference in
altitude doesn't sound much, the differences between the inner and outer atmosphere are actually quite pronounced, with the atmosphere 10 times denser at 125
km than it is
as 150
km.
«During the deep - dip campaigns, we lower the lowest
altitude in the orbit, known
as periapsis, to about 125
km, which allows us to take measurements throughout the entire upper atmosphere.»

MAVEN and other agency assets, such
as the Mars Reconnaissance Orbiter, are under no threat from the cloud, which exists at an
altitude of between 93 miles (150
km) to 190 miles (300
km) above the Martian surface.
Brick - shape aside, Bentley's Bentayga can in theory pull this off if it averages at least 60 mph (96
km / h)
as it blazes up through all the 156 corners of the road to an
altitude of 4,302 m (14,115 ft).
C to over -40 Deg C. in the upper ranges (200mb) and the change in
altitude can vary
as much
as 6
km over a wide spread area exceeding a column of 25 sq
km.
As you go higher into the atmosphere, the temperature decreases at a rate of 9.8 ºC /
km (this is called the atmospheric lapse rate), and the atmosphere becomes transparent at an
altitude where the temperature is 255 K (the calculated temperature of the earth without greenhouse gases!).
The mean annual air temperature at the long - term ELA of 1170 m is -1.5 °C,
as estimated from the Wolverine weather station at 990 m
altitude about 0.5
km west of the glacier.
In that case the surface temperature would still be essentially the same
as without any atmosphere, but the atmosphere would have the adiabatic lapse rate up to an
altitude of about 4
km.
The passage from the first to the second paragraph of Section 3.3 of the paper (incorrectly referred to
as Section 3.2 in my example) results in roughly 200 % RH at 4
km altitude in the first column of air, which was the basis for my example.
In calm weather at 5 am in the bottom 1 - 2
km of air above the surface the ELR can be
as strongly negative (temperature increasing with
altitude)
as the MALR is positive, an ultrastable situation.
As Alan D. McIntire (16:36:32) points out, the surface area of a shell at 8 km altitude is pretty much the same as the surface area of the earth (or rather, an earth - sized sphere

As a quick - and - dirty general rule, BC below 5
km will warm the surface, increasingly so at lower
altitudes.
As seen in the above diagram different ranges of the UV spectrum are absorbed at different
altitudes, the Lyman alpha range is particularly strong and produces large amounts of atomic oxygen down to 70
km that is used in the formation of ozone in the mesosphere.
Removing all CO2 from the atmosphere will bring that 5
km altitude lower (
as the temperature of the surface goes down).
The Spice team - drawn from a number of universities
as well
as Marshall Aerospace - calculates that 10 or 20 giant balloons at a 20
