Project 31,1 - Microbafograph - W. A. Gustafson
The purpose of this project was to measure winds in osone layer
of the atmosphere.
This was accomplished by measuring at several sites
the arrival times of the shock wave reflected from the ozone layer,
Pour aites were opereted:
Ujelang, Wetho, Rongerik, and Exnivwetok.
At each site two stations were operated about one mile apart.
The diff-
erence in arrival times gives the angle of incidence of the shock and
information
veral stations may be combined te give the winds,
ron good shot records were obtained from al) stations except Rongerik, which had high ambiemt wind noise.
However enough
directions are available for the Bikini shot to allow osonosphere wind
and temperature resolution, but this has not yet been accamplished,
