In this study we test a stream function method suggested by Israelevich and Ershkovich for instantaneous reconstruction of global, high-latitude ionospheric convection patterns from a limited set of experimental observations, namely, from the elec

The Carnegie curve shows the variation of the vertical electric field near the Earth's surface with Universal Time. The largest of the three maxima in this variation occurs at the time of maximum thunderstorm activity over the Americas, although this

We report on an attempt to examine quantitatively (but indirectly) the classical picture of the global atmospheric electric circuit: namely, the hypothesis that electric currents flowing from global thunderstorms up into the ionosphere (also known as

Digisonde Portable Sounder 4 (DPS-4) ionospheric F-region drift measurements at the polar cap station Casey (110.5°E, 66.3°S geographic, 80.8°S corrected geomagnetic), Antarctica were used to derive the Casey 1997 (C97) regression model of Smith [

A new technique is proposed for the rapid reconstruction of ionospheric electric fields from plasma drift measurements made by the Sondrestrom incoherent scatter radar. We utilized the adaptive distribution of electric charges over and beyond of the

Vertical geoelectric field measurements at Vostok, Antarctica ( 78.5° S , 107° E ; corrected geomagnetic latitude, 83.4°S) made during 1998 are compared with both Weimer (1996) and IZMEM (1994) model calculations of the solar-wind-induced, polar-c

September 1999 was a magnetically active month, with several geomagnetic storms occurring in sequence which influenced the current pattern of the high-latitude ionosphere. The DMI Greenland magnetometers recorded variations of the ionospheric Hall cu

Applying a new data visualization technique to magnetic field observations from the Greenland west coast array we observe that Pc5 wave power spatial/temporal variations in the morning/pre-noon sector are closely related to the location and intensity

We report on field-aligned currents (FAC) ob- tained from precise magnetic field measurements made on- board the Orsted and Magsat satellites when the interplan- etary magnetic field (IMF) was near zero. We found that Region 1/Region 2 currents persi
