What was discovered
Using hundreds of sounding balloons, Teisserenc de Bort found that temperature stops falling at about 11 km and levels off or rises: the stratosphere, separated from the troposphere by the tropopause. The atmosphere turned out to have layers with distinct physics.
Place where the observations were made. Assmann reached the same result independently in Berlin.
What it led to
- High-altitude meteorology and stratospheric aviation
- Discovery of the ozone layer
- Ionosphere (Appleton, 1924) and mesosphere
Built on
- Balloon ascents by Glaisher and Gay-Lussac
- Recording thermometers
Made possible
- Väisälä's radiosonde1931
- High-altitude aviation
