Addition et Soustraction d'un Nombre à 4 Chiffres par un Nombre à 2 Chiffres (Gros Caractère) (A)

We have presented a comparison between Millstone Hill incoherent scatter radar measurements of electron density and ion and electron temperature with results from the IZMIRAN model

Using the method of superposition of epoches, the mean occurrence probability of F-spread for the set of earthquakes with M > 5.5, R < 1000 km, h < 80 km is calculated..

Ozone vertical profiles derived from nadir mea- surements of the GOME instrument on board the ERS-2 satellite, by means of the FURM algorithm of the Univer- sity of Bremen,

(4) and (5), the values of kx and kz are chosen to be the dominant horizontal and vertical wave numbers at each integer hour (shown in Fig. 2), respectively; the values u; w and ma

The results obtained from the model when the neutral wind is given by HWM90 reproduce the observations that the electron density at 600 km altitude is higher in the summer

change in the calculated wave azimuth. W can also be calculated from the average of the line-of-sight velocities in the o€-vertical beams, i.e. Figure 6 shows a visible-light

In this case we can expect variation of the energetic particle source amplitude (which is proportional to the electron density in a cloud), pitch-angle anisotropy, and

A surprising result was that for pulsation signals away from the local ®eld line resonance (FLR) frequency the phase of the ionospheric Doppler oscillations was found to
