The Low Temperature Laboratory recorded a record low temperature of 100 pK, or 1.0 × 10 −10 K in 1999. [11] The current apparatus for achieving low temperatures has two stages. The first uses a helium dilution refrigerator to get to temperatures of millikelvins, then the next stage uses adiabatic nuclear demagnetisation to reach picokelvins ...
The troposphere is the lowest of the four layers and extends from the surface of the Earth to about 11 km (6.8 mi) into the atmosphere, where the tropopause (the boundary between the troposphere stratosphere) is located. The width of the troposphere can vary depending on latitude: for example, the troposphere is thicker in the tropics (about 16 ...
The troposphere is the lowest layer of Earth's atmosphere. ... The average temperature of the atmosphere at Earth's surface is 14 °C (57 °F; 287 K) ...
The coldest reliably measured temperature in Verkhoyansk was −67.8 °C (−90.0 °F) on February 5 and 7 of 1892. On February 6, 1933, a temperature of −67.7 °C (−89.9 °F) was recorded at Oymyakon's weather station. [5] At the time, this was the coldest reliably measured temperature for the Northern Hemisphere.
The increase of air temperature at stratospheric altitudes results from the ozone layer's absorption and retention of the ultraviolet (UV) radiation that Earth receives from the Sun. [7] The coldest layer of the atmosphere, where the temperature lapse rate changes from a positive rate (in the troposphere) to a negative rate (in the stratosphere ...
Lowest temperature in the Northern Hemisphere: −69.6 °C (−93.3 °F); Greenland Ice Sheet, Greenland on 22 December 1991. [ 198 ] Coldest average monthly temperature in the Northern Hemisphere : −54.1 °C (−65.4 °F); Oymyakon , Russia for the month of January 1931.
The actual temperature at the time of 47 degrees below zero tied with a 1934 record for the lowest temperature ever recorded at the station.
The mesopause is the point of minimum temperature at the boundary between the mesosphere and the thermosphere atmospheric regions. Due to the lack of solar heating and very strong radiative cooling from carbon dioxide, the mesosphere is the coldest region on Earth with temperatures as low as -100 °C (-148 °F or 173 K). [1]
