Word History

Etymology

borrowed from French troposphère, from tropo- tropo- (in sense "change," as the troposphere is where weather changes take place) + -sphère -sphere

Note: The term was introduced, along with stratosphère stratosphere, by the French meteorologist Léon Tesserenc de Bort (1855-1913). Tesserenc de Bort apparently first used them in a paper read to a German meteorological society in Hamburg on September 30, 1908 ("La division de l'atmosphère en troposphère et stratosphère d'après les résultats de l'exploration de la haute atmosphère"). The paper was not subsequently published but is briefly summarized by C. Kassner in "Bericht über die elfte allgemeine Versammlung und Feier des 25-jährigen Bestehens der Deutschen Meteorologischen Gesellschaft zu Hamburg am 28. bis 30. September 1908," Meteorologische Zeitschrift, Band 26, Heft 1 (Januar, 1909), p. 6.
