U.S. Standard Atmosphere Air Properties – Imperial (BG) Units
| Geo-potential Altitude above Sea Level – h – (ft) | Temperature – t – (oF) | Acceleration of Gravity – g – (ft/s2) |

Why does temperature increase with higher altitude?
Answer 5: You are correct that it is colder at higher altitudes. As you go to higher altitudes, there are less air molecules pushing down on you (lower pressure). When the pressure of a gas decreases, the temperature also decreases (the reverse is also true – when the gas pressure increases, the temperature increases).
How does temperature vary with altitude?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases. If the humidity is at 100 percent (because it’s snowing), the temperature decreases more slowly with height.”
How high up can a person breathe?
An elevation of about 20,000 feet above sea level is the maximum height at which sufficient oxygen exists in the air to sustain us.
Why is the temperature lower at higher altitudes?
High-altitude locations are usually much colder than areas closer to sea level. This is due to the low air pressure. Air expands as it rises, and the fewer gas molecules—including nitrogen, oxygen, and carbon dioxide—have fewer chances to bump into each other.
Why does the temperature decrease with altitude?
In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere’s gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.
How do you find the temperature of a place?
That is why cities are often warmer compared to suburbs. It is recommended to keep the thermometer at least 100 ft. from any paved or concrete surfaces to prevent an erroneously high temperature measurement. 5.
How much temperature do you lose when you increase elevation?
You will lose an average 3.5 degrees Fahrenheit for every 1000 feet of elevation you gain. You can also use about 1.2 degrees Celsius per ever 1000 feet, or about 1 degree Celsius per 100 meters (source, NFW who showed me my typo on the metric conversion in the comments).
What is the standard value of atmospheric pressure at high altitude?
Standard values for pressure, temperature and density (ignoring the slight effect of humidity) at altitudes from sea level to 16,000 feet (about 4900 m): 1 ft (foot) = 0.3048 m. 1 in mercury (Hg) = 3,376.8 N/m 2 (Pa)= 0.49 lb/in 2 (psi) = 12.8 in water. T( oC) = 5/9[T( oF) – 32]
How much warmer does it get as you go up elevation?
In sunny weather, subtract about 5.4 degrees Fahrenheit for every 1,000 feet you go up in elevation.
What is the density of air at different altitudes?
Altitude – air temperature and air density. Sponsored Links. Standard values for pressure, temperature and density (ignoring the slight effect of humidity) at altitudes from sea level to 16,000 feet (about 4900 m): 1 ft (foot) = 0.3048 m. 1 in mercury (Hg) = 3,376.8 N/m 2 (Pa)= 0.49 lb/in 2 (psi) = 12.8 in water.
