The thermosphere (or the upper atmosphere) is the height region above 85 kilometres (53 mi), while the region between the tropopause and the mesopause is the middle atmosphere (stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near an altitude of 45 kilometres (28 mi) and causes the ozone layer.
Presently "CIRA 1986" or CIRA-86 covers the height range up to 120 km as a set of tables. In the thermosphere, above about 100 km, CIRA-86 is identical to the more complicated NASA MSIS-86 model. All models are now available on the Web. The task group takes account of more recent data at bi-annual meetings in connection to COSPAR meeting.
These layers are the troposphere, stratosphere, mesosphere, and thermosphere. 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 ...
The Mesosphere, Lower Thermosphere and Ionosphere (MLTI) region of the atmosphere to be studied by TIMED is located between 60 and 180 kilometres (37 and 112 mi) above the Earth's surface, where energy from solar radiation is first deposited into the atmosphere. This can have profound effects on Earth's upper atmospheric regions, particularly ...
The ionosphere, an ionized portion of the upper atmosphere which includes the upper mesosphere, thermosphere, and lower exosphere and on Earth lies between the altitudes of 48 and 965 kilometres (30 and 600 mi)
These corals, which are common throughout the Indo-Pacific region, begin life in one spot but become more mobile as they mature. Dig this The burial site at the Montelirio tomb in southwestern ...
Free-floating brown dwarfs rotate faster than Jupiter and studies have inferred the presence of zonal winds. The brown dwarf 2MASS J1047+21 has a rotation period of 1.77 ± 0.04 hours and it has strong winds with speeds of 650±310 m/s proceeding eastwards.
The thermopause is the atmospheric boundary of Earth's energy system, located at the top of the thermosphere. [1] The temperature of the thermopause could range from nearly absolute zero to 987.547 °C (1,810 °F).
