The daytime equatorial electrojet is a narrow band of enhanced eastward current flowing in the 100 to 120 km altitude region within ±2° latitude dip equator. A unique way determining strength observe difference magnitudes Horizontal (H) component between magnetometer placed directly on magnetic equator and one displaced 6 9 degrees away. these measured H values provides direct measure current, turn, magnitude vertical ExB drift velocity F ionosphere. This paper discusses recent study that has established quantitative relationship ionospheric South American (west coast) longitude sector.
