We use a trio of empirical models to estimate the relative contributions of solar extreme ultraviolet heating, Joule heating and particle heating to the global energy budget of the earth’s upper atmosphere. Daily power values are derived from the m

Simultaneous observations by Wind and IMP-8 in the upstream region on May 11, 1999, when the solar wind density was well below its usual values and the IMF was generally weakly northward, indicate there were upstream waves present in the foreshock, b

The plasmaspheric mass density at L ≃ 2 was monitored by two IGPP/LANL ground magnetometer stations during the magnetic storm on September 25, 1998. Even at this low latitude the plasma density dropped significantly to ≃ 1/4 of the pre-storm valu
