With the exception.of the third burst, the Castle series con-

Bikini Atoll, the succeeding four from barges in the Bikini lagoon
and the last on Eniwetok Atoll.
As shown in Table 2.1, most of the radioactive clowls created
in the Castle series extended to very great heights, with the mush-
observations. For this reason, it has been impossible to prepare
adequate mtecrological trajectories to determine the path of the |
debris at various levels. The network of upper sir observing
stations in the tropics is extremely sparse at best, and wind reports
aq
room of the cloud well in the stratosphere, and the greater part of
the cloud in levels beyond the reach of routine meteorological
at levels above 80,000 feet ere virtully nonexistent, with the
exception of a fewfrom stations in the Mershell Islands and
ary
adjacent areas established especially for this test series. Even
at these stations, the highest observations rarely extend sbove
100,000 ft.
