IONOSPHERIC AND MAGNETOSPHERIC EFFECTS (Nonmicrowave) (Cont’d) F-REGION (Cont’d) 13. Participation in already planned rocket launches (targets of opportunity). Add-on of ground based measurements, acquisition of SPS relevant data. Simulation of effects and comparison with observations. High 6/80 14. Conduct laboratory experiments to determine molecular ion dissociative recombination rates and products (specifically for H20+ and 0H+) High 1/80 15. Examine archived data taken during previous rocket launches to test simulation predictions and to search for radio scintillation effects and traveling ionospheric disturbances (TIDs) associated with gravity waves caused by rocket launches. High 1/80 MAGNETOSPHERE/PLASMASPHERE/SATELLITES 16. Theoretically investigate time-dependent response of plasmasphere to argon ion injection and the impacts on electromagnetic wave propagation. High 1/80 17. Determine modification of radiation belt high- energy electrons and associated radiation dosage environment. High 1/80 18. Estimate changes in airglow. Medium 9/79 19. Measure diurnal variations in natural plasma- spheric properties. Medium 9/80 20. Conduct depletion experiments at auroral latitudes (add-on to planned experiment). Medium 9/80 21. Use existing data to investigate mechanisms for dumping and replenishing trapped particles. High 1/80 22. Investigate impacts on satellite and terrestrial environments of 30 to 60 SPS satellites in GEO. (Source of dust debris, plasma waves, induced electric and magnetic field effects, light reflection, diffuse infrared and microwave radiation.) Medium 1/80
