Temperatures range from an average of −51 °C (−60 °F; 220 K) near the tropopause to an average of −15 °C (5.0 °F; 260 K) near the mesosphere. [5] Stratospheric temperatures also vary within the stratosphere as the seasons change, reaching particularly low temperatures in the polar night (winter). [6]
The U.S. Standard Atmosphere is a set of models that define values for atmospheric temperature, density, pressure and other properties over a wide range of altitudes. The first model, based on an existing international standard, was published in 1958 by the U.S. Committee on Extension to the Standard Atmosphere, [ 9 ] and was updated in 1962 ...
The graph also shows the typical phenomenon of increased temperature ranges during winter. In Campinas, for example, the daily temperature range in July (the coolest month of the year) may typically vary between 10 and 24 °C (range of 14 °C), while in January, it may range between 20 and 30 °C (range of 10 °C).
The stratosphere defines a layer in which temperatures rise with increasing altitude. This rise in temperature is caused by the absorption of ultraviolet radiation (UV) from the Sun by the ozone layer, which restricts turbulence and mixing. Although the temperature may be −60 °C (−76 °F; 210 K) at the tropopause, the top of the ...
[24] [25] There has been a decline in stratospheric temperatures, interspersed by warmings related to volcanic eruptions. Global Warming theory suggests that the stratosphere should cool while the troposphere warms. [26] Top of the stratosphere (TTS) 1979–2006 temperature trend.
Black carbon in the atmosphere is like dressing Earth in a black shirt on a sunny day.
TMT and TLT represent the altitude range computed lower troposphere temperature calculated using an atmospheric model as discussed below. The T4 or TLS channel in representative of the temperature in the lower stratosphere with a peak weighting function at around 17 km above the Earth surface.
