Atmosphere of Earth that gas. The stratosphere defines a layer in which temperatures rise with increasing altitude. This rise in temperature is caused by the absorption of ultraviolet radiation (UV) radiation from the Sun by the ozone layer, which restricts turbulence and mixing. Although the temperature may be at the tropopause, the top of the stratosphere is much warmer, and may be near 0 °C. The stratospheric temperature profile creates very stable atmospheric conditions, so the stratosphere lacks the weather-producing air turbulence that is so prevalent in the troposphere. Consequently, the stratosphere is almost completely free of clouds and other forms of weather.
Earth Radiation Budget Satellite was one of three satellites in the ERBE and it carried two instruments as part of that effort. The ERBE scanner was a set of three detectors that studied longwave radiation, shortwave radiation and total energy radiating from the Earth along a line of the satellite's path. The ERBE non-scanner was a set of five detectors that measured the total energy from the Sun, and the shortwave and total energy from the entire Earth disk and the area beneath the satellite. The other two ERBE missions were included on the NOAA-9 satellite when it was launched in January 1985, and
