Stratosphere the stratosphere temperatures increase with altitude "(see temperature inversion)"; the top of the stratosphere has a temperature of about 270 K (−3°C or 26.6°F). This vertical stratification, with warmer layers above and cooler layers below, makes the stratosphere dynamically stable: there is no regular convection and associated turbulence in this part of the atmosphere. However, exceptionally energetic convection processes, such as volcanic eruption columns and overshooting tops in severe supercell thunderstorms, may carry convection into the stratosphere on a very local and temporary basis. Overall the attenuation of solar UV at wavelengths that damage DNA by the ozone layer allows
Lauriston S. Taylor Lauriston S. Taylor Lauriston S. Taylor (1 June 1902 – 26 November 2004) was an American physicist known for his work in the field of radiation protection and measurement. He established standards for X-ray radiation exposure for the first time in the 1920s, which eventually led to a group of government organizations that set the standards over the next 50 years. Taylor remained active in debates about radiation exposure into his 80s, often advocating the viewpoint that small doses of radiation were not important. He served as president of the Health Physics Society (HPS) from 1958 to 1959. He was
