Abstract: | The magnitude, dissipation mechanism, and spatial distribution of the solar wind - magnetospheric energy source are discussed briefly. Using N2 measurements of the ESRO 4 satellite, the temperature increase in the polar thermosphere associated with this energy source are investigated. Part of the locally dissipated energy is transported toward lower latitudes. Possible modes of energy transfer are reviewed, and local time variations are documented. Some suggestions are made with respect to future empirical models of the thermosphere. |
