Abstract : Documentation of meteorological parameters occurring just prior to, during, and for a period after each of the four events of the series was the primary object of Project 2.4 (Micro-meteorological measurements). The meteorological parameters desired were wind speeds and directions from the surface to 3,000 ft above it, temperature profile in the same layer, and turbulence measurements. The wind data and temperature data were required to be continuously monitored at the control point during each event. This required various types of telemetering and communications. Surface wind data were collected using sensors on 30-ft towers at locations in the downwind array. M-33 radars sited along the border of each array, with remote release points down the array centerlines, were used to obtain event winds-aloft profiles. Two 120-ft United Kingdom (UK) towers near each GZ supplied additional wind data at the 60-ft and 120-ft levels plus gustmeter data for turbulence evaluation. Pibal crews obtained gross scale wind features for use by event weather briefers. A tethered United Kingdom balloon with sensors at 100-ft intervals obtained vertical temperature profiles. Also at each event shot time, United States Weather Bureau (USWB) personnel obtained a temperature sounding using modified rawinsonde equipment. (Author)
