Objective: Investigation of part of the Earth\'s global electrical
circuit: the fair weather current and its interaction with geomagnetic
phenomena, such as, for example, magnetic substorms. We use data of the air-earth current measured by a long wire antenna installed
in Kiruna/Esrange, Sweden. In July 1999 we installed a new
portable antenna at a distance of about 30 km from the old one.
This antenna has a length of nearly 50 m, and we are recording the
near-ground vertical current with a time resolution of 10 seconds.
The data from both instruments will be analysed together - for comparison
and possible separation of the meteorological effects.
Responsible scientists: Evgenia Belova
