Sub ELF Geomagnetic Fluctuations. Volume III. Observations of Transient and BackGROUND VLF, ELF and Sub ELF Electromagnetic Effects Produced by High Altitude Nuclear Detonations

摘要

The report deals with two completely separate categories of ELF and sub ELF effects produced by high altitude nuclear detonations. In the first category are electromagnetic transients produced by the explosions. In the second category are variations in background effects resulting from bomb-produced changes in the electromagnetic environment. Part 1 discusses the operation of the Lockheed Pacific stations and the instrumentation employed for the ELF and sub ELF measurements. Part 2 presents results of geomagnetic fluctuations and electromagnetic waves produced by high-altitude nuclear detonations in the summer of 1962 series. Also presented are signals from three high-altitude tests conducted by the USSR. Part 3 considers bomb-produced variations in background electromagnetic radiation. The results of this section are limited to a single event (9 July 1962), but data is presented in a broad frequency range extending through the VLF band.
