Mean monthly occurrence frequencies of Kp index in di€erent magnitude ranges as a function of the phase of the solar cycle: minimum (Min); ascending (Asc); maximum (Max); and

(aa) the leading edge of the E-layer and the equatorward edge of the di€use luminosity belt are physically the same: (bb) the F-layer boundary blob echoes can be observed until

Several individual topics are then discussed, including eclipse e€ects, the asymmetries of the `equatorial trough', variations with longitude, the semiannual variation, the e€ects

Fig. A schematic representation of the relative locations of the MSP meridian and the Sunward-¯ow region of backscatter under the time dependent interpretation of the observations.

The event is strongly localized in radial direction at approximately L ˆ 5 and exhibits properties of a ®eld line resonance such as an ellipticity change as seen by applying the

DASI is well suited to make Pedersen conductance estimates everywhere within STARE's ®eld-of-view as it is calibrated, automatically makes column integrals of total optical

abies may be either limited soil water reserves or atmospheric evaporative demand depending on the current level of the vapour pressure de®cit.. As the soil dries the stomatal

Assuming a wave source at the auroral electrojet height of ∼125 km, and wave ascent an- gles consistent with the properties of gravity waves, we find source locations for the
