How does the atmosphere change at you go up high in the sky?
Dropsondes are launched from aircraft to measure temperature, wind, humidity and pressure as they fall through the sky.

The electromagnetic (EM) spectrum spans many types of radiation, from long-wavelength radio waves, through infrared, visible, and ultraviolet "light" and gamma rays and x-rays.
The exosphere is the uppermost region of Earth's atmosphere as it gradually fades into the vacuum of space. The air in the exosphere is extremely thin - in many ways, it is almost the same as the airless void of outer space.

Layers of Earth's atmosphere: troposphere, stratosphere, mesosphere, thermosphere and exosphere.
Resource Type: Information
The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet.
In the stratosphere is the ozone layer, which keeps much of the harmful UV radiation from the Sun from reaching us on the surface.
