10 Οκτ 2024 · Global mean thermosphere density trends for 2015–2070 were shown to be about twice as large as for the period 1950–2015, as expected for a more rapid increase in CO 2 concentration.
13 Μαΐ 2019 · What are the spatial and temporal scales and the variability of atmospheric waves in the thermosphere, what is their latitudinal structure, and what is their role in driving large-scale circulation in the mesosphere and lower thermosphere?
5 Ιαν 2022 · Climate change is an unintended consequence of the industrialization of the world economy. The evidence that human activity has released large amounts of CO2 into the atmosphere, leading to rising global temperatures, is by now uncontroversial.
18 Αυγ 2021 · The four themes supported under ROSMIC are solar influence on climate, coupling by dynamics, trends in the mesosphere lower thermosphere, and trends and solar influence in the thermosphere. Over the course of the VarSITI program, scientific advances were made in all four themes.
For our daily lives and routine economic activities on planet Earth, the conditions within the Earth's magnetosphere, ionosphere and thermosphere are particularly important as dynamic changes in the environment caused by the Sun and the solar wind can influence the functioning and reliability of spaceborne and ground-based systems and services ...
The thermosphere contains an appreciable concentration of elemental sodium located in a 10-kilometre (6.2 mi) thick band that occurs at the edge of the mesosphere, 80 to 100 kilometres (50 to 62 mi) above Earth's surface. The sodium has an average concentration of 400,000 atoms per cubic centimeter.
Synopsis. The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity.
