FURTHER EXPERIMENTATION
The results indicate tha possibility of widespread disruption

of radio commmications due to absorption, presumably caused by windborne radioactive material at high altitudes. The lateral extent
of this effect is still unknown.
It is therefore recommended that,
during future large-scale tests, experiments be performed to more
accurately locate the bouridaries and motion of the material causing
the absorption. Such experiments eeuld be carried out with an airborne ionosphere recorder. Data so obtained, combined with data
taken concurrently at suitably located ground stations, would also be
of great value in gaining a more complete picture of the convection
resulting from large blasts and of the
associated ionic motions.

COMPREHENSIVE DATA ANALYSIS
woo.
.
Many of the phenomena observed during Operations IVY and CASTILE
are similar to effects that usually accompany ionospheric storms. It
is therefcre recommended that a comprehensive study be made of the
‘>
data already obtained in combination with related data from futura
tests. Such a study should lead to a more complete understanding of

the processes involved in naturally caused phenomena.
CONTINUED STUDY OF DISTANT DATA
It is recommended that ionosphere records at distant locations
continue to be examined for evidence of traveling lonosphsric disturb-
ri
abe
ances initiated by large explosions.
Data on the velocity of prop~
agation of such disturbances in different directions from a know
source cannot be obtained by any other means.
