Brief Description (Abstract):

We are operating atmospheric electrical instruments like long wire antenna, electric field meter, wire antenna and passive antenna for atmospheric Maxwell current, electric field, conduction current and atmospheric potential gradient. This year (December 2008) we have installed Electric Field Meter (EFM-100) and wire antenna for measuring the atmospheric electric field and conduction current. This instrument is deployed at Maitri, Antarctica and will be operated under any weather conditions like snow fall and strong blizzard etc., The study has been carried out during austral summer for the period of 2008 and 2009 at the Indian station, Maitri (70.75? S, 11.75? E, 117 m above mean sea level). The present work has been to understand the new instrument system in response to different meteorological conditions and on fair weather days. The measured electric field from the Passive antenna and EFM-100 compared and is behaving similar variation.

Status: Completed

Purpose: Detailed study about the upper atmospheric contribution will be carried out after reaching to the mainland. With the continuous measurements of atmospheric electrical parameters and geomagnetic field variations, there is scope for addressing the problems related to the modulation of GEC by the influence of magnetosphere-ionosphere -lower atmosphere coupling processes on the near-surface electrical parameters in the polar caps.
