Castle Test Series
(MI)
1810
The first burst was detonated on
Bikini Atoll, the succeeding four from barges in the Bikini lagoon
and the last on Eniwetok Atoll,
most of the radioactive clouds created
in the Castle series extended to very great heights,
and the greater cart of
the cloud in levels beyond the reach of routine meteorological
observations. For this reason, it nas been impossible to prerare
adequate meteorological trajectories to determine the cath of the
debris at various levels.
°
The network of upper air observing
stations in the tropics is extremely scarse at best, and wind reports
at levels above 40,000 feet are virtually nonexistent, with the
exception of a few from stations in the “arshall Islands and
adjacent areas established especially for this test series. Even
at these stations, the highest observations rarely extend above
100,000 ft.
