Ww ) rca) Project 31.1 = Miarebarogreph ~ W, A. Oustafsen The purpese of this preject was to measure winds in esone layer ef the atmosphere. This wee accompliahed by measuring at several sites the arrival tines of the shook wave reflected fram the osene layer. Five aites were operated: wetek, Ujelang, Wctho, Rongerik, Bikini, end Bni- At each site two stations were operated about one ile apart. The difference in arriva) times gives the angle of ineidence ef the . shook ond information from several stations any be combined to give the winds. 3) trwca) geod shot records were obtained from all stations except Rengerik, wrich had kigh ambient wind noise. ‘The satisfactery Bikini recerd will allow osonesphere resalution but no temperature and wind vectors are yet available, BEST AVAILAB LE COPY - 55 - core S “3 &
