Scientific Discipline Middle atmosphere: composition and chemistry

Atmospheric Sciences
A view of the blue haze of the Earth’s atmosphere

Research Spotlight 21 November 2018

Satellite Observations Validate Stratosphere Temperature Models

Since the 1970s, the stratosphere has cooled as ozone levels dropped and carbon dioxide levels increased. Chemical models of the temperature decline conflicted with satellite observations—until now.
