The Atmospheric Air Ions and Air-Earth Current Density Measurements at Maitri.

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

Brief Description (Abstract):

Simultaneous measurements of the small, intermediate and large-positive ions and air-earth current density made at Maitri during January ? February 2005 are reported. Variations in small and large positive ion concentrations were almost similar to each other. On the other hand, variations in intermediate positive ion concentrations were independent of the variations in the small/large positive ions and exhibited a diurnal variation which was similar to that in atmospheric temperature on fair weather days with a maximum during the day and minimum during the night hours. No such diurnal variation in intermediate positive ion concentration was observed on cloudy days when variations in them were also similar to those in small/large positive ion concentrations. Scavenging of ions by snowfall and trapping of a-rays from the ground radioactivity by a thin layer of snow on ground, was demonstrated from observations.

Status: Completed

Purpose: An opportunity for such a study was provided during our measurements of some atmospheric electric parameters and aerosols during the 24th Indian Scientific Expedition to Antarctica.
