Description:
(Meteorologist) Léon Philippe Teisserenc de Bort, a French meteorologist, made significant contributions to the field of aerology. Alongside Richard Assmann, he co-discovered the stratosphere in 1902. Teisserenc de Bort pioneered the use of unmanned instrumented balloons to gather atmospheric data. He identified the tropopause, a region in the atmosphere around 8-17 kilometers in height where the lapse rate reaches zero. His work laid the foundation for our understanding of the Earth's atmosphere and its different layers.
