“…It is of interest to note that Smirnov [] reported the variation of the atmospheric electric field measured at Kamchatka (52.9°N, 158.25°E; mag: 46°N) on 5 April 2010. He reported that a sharp PG enhancement was observed during our second interval (08:24–11:30 UT) and no further variations were addressed on account of this geomagnetic perturbation (Figure in the reference), because the magnetic perturbation during the second interval is considerably strong so that its magnetospheric field influence may penetrate up to the middle latitude, which in turn alters the PG.…”

The effects of a geomagnetic storm on the variation of the atmospheric electric field over Maitri (70°45′S, 11°44′E), Dome C (75°06′S, 123°20′E), and Vostok (78°27′S, 106°52′E) Antarctic research stations are presented in this paper. For the first time, the paper reports the simultaneous observations of the atmospheric electric field/potential gradient (PG) over the three high‐latitude stations at the Southern Hemisphere, and its associated changes due to a substorm phenomenon. PG data obtained from these three stations under fair‐weather conditions on 5 April 2010 are analyzed. The duration of geomagnetic disturbance is classified into three intervals, which contains three consecutive substorms based on the magnetic records of the Maitri station. The substorm is directly related to an enhancement of the magnetospheric convective electric field at high latitude, generally controlled by the solar wind parameters. It is found that the variation in the amplitude of PG depends on the magnetic latitude during substorm onset. During the substorm expansion phase, when the convection cell is at overhead, PG is significantly enhanced due to the downward mapping of the ionospheric horizontal electric field. The present observation demonstrated the changes on PG due to the spatial extension of the convection cell from high latitudes up to middle latitudes.

“…Dolezalek (1992), citing Benndorf's calculations, stated that the PG values are representative if the distance between the measuring sensor and any field-distorting disturbance is five times the height of that disturbance or three times the height for thin obstacles such as poles. Our site meets these conditions; other stations have similar site characteristics (Kumar et al 2009;Piper and Bennett 2012;Smirnov 2014).…”

In the current work, 4 years of atmospheric electric field observations at a rural site near Xanthi, Greece, are presented for 2011-2014. The site is situated in an area with very high radon fluxes and high thunderstorm activity. The annual variation is consistent with that at other Northern Hemisphere continental stations, with maxima (minima) occurring during the cold (warm) months. The diurnal variation of the atmospheric electric field both for fair weather (FW) and all weather is found to exhibit a double-peak structure corresponding to local effects and global thunderstorm activity. Comparison with the Carnegie curve shows that nighttime hours and winter months are preferable for observing the Global Electric Circuit at the Xanthi site. Finally, it is shown that atmospheric CO 2 measurements can be effectively utilized as a stratification proxy, indicating conditions of potential radon trapping, whereas CO 2 was found to anticorrelate with the atmospheric electric field during such conditions.

“…Such forms of signals were excluded from the database of PG negative anomalies. Negative bays in PG measurements may also occur during magnetic storms [21]. The paper used local K-indexes of magnetic activity from Paratunka observatory, which is included in the Intermagnet network.…”
