Magnetic anomalies at high altitudes
To investigate the effect of anomalies in the Earth's magnetic field at high altitudes, aeromagnetic maps of two representative areas showing isanomalic curves for total intensity are projected to levels of 10 and 20 miles above the surface of a plane Earth. The projections are accomplished by numerical computations and by use of a magnetic‐field projecting machine at the Naval Ordnance Laboratory. It is found that anomalies of 500 gammas near the surface of the Earth, in merging into neighboring anomalies, may produce effects of 100 gammas or more at an altitude of 20 miles.
