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.
27 Φεβ 2020 · Key Points. Winds and currents dependent on external drivers and internal processes need improved descriptions. Coupling to the magnetosphere should include hemispheric differences in energy and mass flow. Formation and evolution of multiscale structures require detailed investigation. Plain Language Summary.
29 Δεκ 2014 · The Mars Global Ionosphere-Thermosphere Model (MGITM) is presented and validated; MGITM captures solar cycle, seasonal, and diurnal trends observed above 100 km; MGITM variations will be compared to key episodic variations in future studies
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.
18 Μαρ 2015 · The dynamics of the mesosphere-lower thermosphere (MLT) (60 to 110 km) is dominated by waves and their effects. The basic structure of the MLT is determined by momentum deposition by small-scale gravity waves, which drives a summer-to-winter pole circulation at the mesopause.
2 Φεβ 2023 · Nature Geoscience - Spacecraft observations and climate modelling have revealed how atmospheric waves, dust storms and atmospheric loss processes are coupled throughout the atmosphere of Mars.
