noun ˈtrəʊpə(ʊ)sfɪəˈtrɒpə(ʊ)sfɪəˈtrɑpəˌsfɪ(ə)r
The lowest region of the atmosphere, extending from the earth's surface to a height of about 6–10 km (the lower boundary of the stratosphere).
Example sentencesExamples
- Also, the presence of stratospheric ozone sandwiched between the satellite and the troposphere makes seeing tropospheric ozone very difficult.
- The other two climate records, so-called ‘upper air’ records, measure temperatures in Earth's troposphere and stratosphere.
- The stratosphere extends above the troposphere to about 150,000 feet and is the region where the ozone layer is formed.
- The stratosphere is the atmospheric layer between the troposphere and the mesosphere and extends from about 12 km altitude to about 50 km.
- Because of the cloud spreading at the top, the height of the troposphere in the area can also be calculated.
Origin
Early 20th century: from Greek tropos 'turning' + sphere.
