The assumptions are that substorms expansions are the unloading of magnetic energy stored in the tail and that of the energy thus unloaded more goes into the ionosphere as Joule

Time evolution of the (NO) mixing ratio in the model box: 1, narrow plume; 2, basic, 3, wide plume, and circles, measured (NO) in cross section of various exhaust plumes over

Two conclusions are reached: (1) with an optimal set of solar-wind data available, the AE predictions are not markedly improved by the Dst input, but (2) the AE predictions are

Thermal, pressure and wind fields at ground level in the area of the Italian base at Terra Nova Bay, Victoria Land, Antarctica, as observed by a network of automatic weather

From comparison of ground observations of auroral forms with meridional pro®les of particle ¯ux measured simultaneously by the low-altitude NOAA satellites above the ground

In layer 1 there are no magnetic field components for the VED (i.e. Computations of the electric field compo- nents are made following the procedure described in Sect. 4.2 using

In order to quantify the relative importance of the QBO cycle with respect to the annual variation in UV erythemal dose, we calculated the peak-to-peak amplitudes of the an- nual

We applied the procedure to a baseline analysis of the perfor- mance of a recently proposed solar UV occultation sensor (SMAS – Sun Monitor and Atmospheric Sounder) and pro- vide,
