which these balloons may hava reached will require further st~. The perfo~e of these balloons was not entirely satisfactory. A large number were defective and burst at elevations below 60,000 feet. The Eniwetok stationwas also equipped with SCR 584 Radar @et. Thla set was originally scheduled for diffusion experismts. However, previous mns when evaluated indicated that these nmasuremmts would not supply the answere deoired. As result, the radar was available for use at all times for wind eoundings. This radar aet was able to make whd eoundings to 60,(X)0feet every two hours. The ships of the task force were equipped tith staniani ship radar gear. These radar titallatiorw were not too well suited for making wiml runs. The ships were equipped with the stamiami type radlosode apparatus, e~gs ami with scum modificationswera able to eecure equally well as the land baaed stations. Were praotkable helium should be substituted for hydrogen generation ●quipamnt. This substitutionie suggested as being advantageous fmm several different points, orm, it is less dangeroua, aecomily it is much more convenient to handle than the chemica3s, requiring less rnn. Some @nsideration might be given to developing equi~nt shipboard operation to read the wind direction ad 6. Comunicationse SECTION XII n for velocity directly.
