Effective Recombination Coefficient of the Polar D-Region Under Conditions of Intense Ionizing Radiation.

Abstract

The intense solar-particle event in August 1972 produced high levels of ionization at altitudes of 60 to 90 km over the DNA/SRI Incoherent Scatter radar located at Chatanika, Alaska. The magnitude of the instantaneous ionizing fluxes at times approached those expected from the beta flux densities following some high-altitude nuclear detonations of interest in system problems. The cumulative radiation doses, leading to build-up of unusual molecules, were probably comparable to those expected from some high-altitude nuclear detonations. These ionizing fluxes were measured by the Lockheed 1971-089 polar-orbiting satellite.
