Abstract

Empirical and analytical techniques for modeling ionospheric fields in Magsat data have been developed that facilitate ionospheric field removal from uncorrected anomalies to obtain better estimates of regional lithospheric anomalies. This task has been accomplished for equatorial ΔX, ΔZ, and ΔB component and polar ΔZ and ΔB component measurements. Data-processing techniques include retention of common signal in a correlation analysis of adjacent passes; analysis of field differences between dawn and dusk data at points where their orbits cross; and retention of common signal in a covariant spherical harmonic analysis procedure. -from Authors
