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

We ®nd, for instance, that in cases where the electron temperature is striated along B0 and low frequency waves (x  Xci) are excited in this environ- ment, for instance by a

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,

The role of vertical transport by cloud convection on the observed seasonal cycle of the surface concentration has been noted by the modelling study of CFCl 3 and CF 2 Cl 2 over..
