Atmospheric global circuit variations from vostok and concordia electric field measurements
Atmospheric electric field measurements from the Concordia station on the Antarctic Plateau are compared with those from Vostok (560 km away) for the period of overlap (2009-11) and to Carnegie (1915-29) and extended Vostok (2006-11) measurements. The Antarctic data are sorted according to several s...
