Summary[edit]

Description
Deutsch: Das schematische Diagramm zeigt das Spektrum der von der Atmosphäre abgegebenen Wärmestrahlung. Im Gegensatz zu einem Planckschen Spektrum (hellbraun zum Vergleich) besteht das Atmosphärenspektrum (blau) aus mehreren deutlich unterscheidbaren Spektralbanden, zwischen denen deutliche Lücken klaffen. Die Banden, hier als durchgehende Flächen dargestellt, bestehen in Wirklichkeit aus einer Unzahl aneinandergedrängter einzelner Spektrallinien. Die Strahlung wird von den Treibhausgasen in der Atmosphäre abgegeben, nicht von Sauerstoff und Stickstoff, welche infrarot-inaktiv sind. Die insgesamt abgegebene Strahlungsleistung ist geringer als die von einem Schwarzen Körper derselben Temperatur emittierte Leistung.
English: The schematic diagram shows the spectrum of the thermal radiation emitted by the atmosphere. Unlike a Planckian spectrum (shown in light brown for comparison) the atmospheric spectrum (blue) consists of several distinct spectral bands, with large gaps in between. The bands, shown solid here, actually consist of a large number of tightly packed single spectral lines. The radiation is emitted by the greenhouse gases in the atmosphere, not by oxygen and nitrogen which are inactive in the infrared. The total power radiated is less than that emitted by a black-body of the same temperature.
