Airglow emissions may be induced by the interaction of atmospheric constituents with vapors released from space vehicles. Such emissions can be produced by a number of chemical mechanisms. This study considers neutral-plasma reactions as well as neutral-neutral reactions as the sources for excited species. The intensities of light emissions produced by the release of water and methyl alcohol into the upper atmosphere is estimated with a numerical mode. Chemical reactions ...
Plasma waves observed during a magnetotail barium release are described. Electron plasma oscillations provided local measurements of the plasma oscillations provided local measurements of the plasma density during both the expansion and decay phases. Immediately after the explosion the electron density reached a peak of about -400000/cc, and then started decreasing approximately as (t to the -2.4th power as the cloud expanded. About 6 minutes after the explosion the electron ...
A detailed description and analysis is presented of the Lagopedo II results. The rocket was launched on 11 September 1977. Prior to an explosive chemical release, a rocket-borne ion mass spectrometer and dual-frequency beacon measured the ion composition and electron content of the undisturbed F region above Kauai, Hawaii. These results are compared to a detailed calculation of ionospheric ion densities. Considerable H2O outgassing produced measurable 18(+)(H2O(+)) and 19(+)(H3O(+)) currents ...
