Lo itaeee ee ee ee 6.4 ~~ oe - CLIMATOLOGY OF THE STRATOSPHERE ‘The special efforts expended in making extra meteorological . observations during the various Pacific atomic tests have produced valuable and unusual data - especially at great elevations. A brief resumé of this-information follows along with reference to the analysis of that data. While it is dangerous. to assume that meteorological data of one location can be considered representative of any other location, this section is based on the only direct observations ever made in the equatorial stratosphere and as such is the best climatological data available for planning purposes. For exanple, it may be of interest to have some knowledge of .the probable path of the middle stratospheric debris if high level sampling is contemplated. The data above 55,000 feet obtained during Operation SAND- STONE and GREENHOUSE have been collected and analyzed by the group under Dr. C. E. Palmer. The results have not been published, but dash mates preliminary results are the subject of two reports (1) to the sponsoring agency. ; , Dependable wind observations were made in the Marshall. Islands - dn the spring of 1951 and the fall of 1952 and the Navy made a total of 19 observations at Palmyra during April and May 1951. A peattering of data from other stations.is also available. The ‘sample is small and confined to short periods of time, but certain SO - Sl :
