The first burst was detonated on

and the last on Eniwetok Atoll.

most of the radioactive clows created
in the Castle series extended to very great heights,
and the greater part of
the cloud in levels beyond the reach of routine meteorological
observations. For this reason, it has been impossible to prepare
adequate meteorological trajectories to determine the oath of the
debris at various levels. The network of upper air observing
stations in the tropics is extremely sparse at best, and wind reports
at levels above 40,000 feet’are virtually nonexistent, with the
exception of a few from stations in the Marshall Islands and
adjacent areas established especially for this test series. Even
at these stations, the| highest observations rarely extend above
100,000 ft.
