Open full text 1 citations

Abstract

The latitudinal geomagnetic variation of the element H, D, and Z at eight Indian Observatories from about 0 to 220 dip latitude have been studied. It is observed that the day-day variability of Sq (H), Sq (D) and Sq (Z) exhibit latitudinal variation. The latitudinal variation is found to be dependent on the position of the station from the equator. The latitudinal variation peaking around the dip equator suggests that one of the possible causative factors is the electrojet strength at the station near the dip equator. The latitudinal variation is independent of local time. Nigeria Journal of Pure and Applied Physics VOLUME 1, AUGUST 2000, pp. 3-4
