ABSTRACT:
There is disclosed method and apparatus for triggering a substantial change in ionospheric characteristics of the earth and measuring certain selected characteristics of the earth. Substantial energetic particle precipitation is triggered through injection of low energy ionized gas, such as hydrogen, in the region of large fluxes of energetic particles in or near the magnetic equator. The loss process is known to occur naturally but a triggered change is achieved through injection of larger amounts of low-energy ionized gas than are naturally present, preferably in the cusp region, which usually extends inside the synchronous orbit for several hours about local midnight.
