Estimation of magnetospheric plasma parameters from whistlers observed at Low Latitudes

Abstract

Whistler observations during nighttimes made at low latitude Indian ground stations Jammu
(geomag.lat.,29o 26/ N; L = 1.17), Nainital (geomag.lat.,19o 1/ N; L = 1.16) and Varanasi (geomag.lat.,14o
55/ N; L = 1.11) are used to deduce electron temperatures and electric field in the vicinity of the
magnetospheric equator. The accurate curve fitting and parameter estimation technique are used to compute
nose frequency and equatorial electron densities from the dispersion measurements of short whistlers
recorded at Jammu, Nainital and Varanasi. In this paper our aim is to estimate the Magnetospheric
electron temperatures and electric field from the dispersion analysis of short whistlers observed at low
latitudes by using the different methods, the results obtained are in good agreement with the results reported
by other workers.
