Froject 6.3 ~ EFFECTS OF ATOMIC EXFLOSIONS ON THE IONOSPEERE
- Major Mathew Hawn
The objective of Project 6.3 is to obtain data on the effects of high yield
i. .¢lear explosions on the Icnosphere,
Principally, to investigate the cicza of
sbsorption, probably due to the high altitude redicactive particles, and to ctudy
the effect of orientation relative to the earth's magnetic field on F2 leyer
effects.
