Evaluation of Geomagnetic Activity in the Mad Frequency Band (.04 to 0.6 Hz)

Abstract

After defining geomagnetic noise as it applies to MAD, the geomagnetic indices currently used by the fleet to predict MAD geomagnetic noise are reviewed to determine their actual applicability. The current indices are determined to be insufficient, methods are proposed for establishing a new MAD index, and a developmental MAD index system was tested. Geomagnetic fluctuations in the .04 to 2.0 Hz frequency band was recorded at Monterey, California, and used for a preliminary test of the proposed MAD index.
