Observations of Atmospheric Maxwell Current at Indian Antarctic Station, Maitri.

Access URI: http://data.ncaor.gov.in/newhtml

Brief Description (Abstract):

Measurements of atmospheric Maxwell current, the fundamental parameter of the global electric circuit was commissioned at Indian Antarctic Station, Maitri, in December 1999. The horizontal long wire antenna is used as a sensor for picking up charges that constitute various currents collectively called the Maxwell current.

Status: Completed

Purpose: The objective of the present work is to understand the response of the experimental setup to various atmospheric electrical and meteorological conditions and to explore the possibilities of detecting the global DC component believed to be the result of global thunderstorm activity. During the fair-weather conditions i.e. days with low or moderate winds, no snowfall or snowdrift, no clouds and no fog effects, the diurnal variation of air-Earth Maxwell current has single periodic with a minimum at 0300 UT and a maximum at 1900 UT. The diurnal variation closely follows the trend of the Carnegie curve.
