Summary

Reference IUGG-2058, Symposium M03 Weather and the Global Atmospheric Electric Circuit. Atmospheric electric field measurements from Concordia station on the Antarctic Plateau are compared with those from Vostok (560 km away) for the period of overlap (2009-2011) and to earlier Vostok (2006-2009) and Carnegie (1915-1929) measurements. The Antarctic data are sorted according to several sets of criteria for rejecting local variability to examine a local summer-noon influence on the measurements and to improve estimates of the global signal. The relatively small contribution to ionospheric potential and surface electric field of the solar wind influence is evaluated and removed, giving monthly-average diurnal variations which reflect the seasonally changing output of the thunderstorms and electrified cloud generators at low latitudes.
