Figure 1From: Response of the mesosphere-thermosphere-ionosphere system to global change - CAWSES-II contribution Trends in the Earth's atmosphere. The atmospheric layers are defined by the temperature profile. The ionospheric layers are defined by the electron density profile (midnight at equator). Arrows indicate the direction of change. Red - warming, blue - cooling, green - no change of temperature, black - changes in electron density (horizontal) and heights of ionospheric layers (vertical). After Laštovička et al.
