Applications of high power microwaves at atmospheric modification and measurement

Summary form only given, as follows. Proposals to use high-power microwaves (HPM) in the atmosphere are discussed. HPM has been proposed to aid in the conservation of stratospheric ozone by partial breakdown, facilitating chemistry to eliminate chlorine. Another proposal is over-the-horizon radar using a partial breakdown area in the ionosphere. A key to any such effort is rapid diagnosis of the state of the atmosphere before, during, and after intervention. Technology requirements of these modification and measurement proposals have been reviewed. The elements of an atmospheric modification program have been identified, and political, economic, and ideological factors have been considered.
