Book Description
An empirical relationship between the area in which a given dosage is equalled or exceeded and the value of the dosage itself are developed using Green Glow data. It is found that the logarithm of the area is nearly a linear function of the logarithm of the dosage divided by the source strength and multiplied by a representative wind speed. These results differ only slightly from similar results obtained from Prairie Grass data. Observations of the time of first arrival of the tracer near ground level at distances of 8 and 16 miles from the source indicate that the tracer material which first arrives has travelled with a wind speed greater than the surface wind (about 15 ft). It would be necessary to have wind speed measurements between 50 and 100 ft above ground in order to estimate the time of first arrival at these distances even though the source is no higher than 15 ft.

Book Description
Published herein are the papers presented at the second annual AFCRL Scientific Balloon Symposium covering the advances shown in balloon design, materials, instrumentation, meteorology, and scientific applications since the last symposium held in Boston on 25, 26 and 27 September 1963. Balloon technology presentations include stress studies, new balloon films, sensing elements, telemetry systems and a new balloon locating system. Applications and experience in working with tethered, meteorological and sounding balloons are discussed. In addition, information is presented on such existing programs as BAL-AST, and Surveyor and such proposed projects as the "AFCRL Stratospheric Humidity Program" and "The Mars Balloon."

Book Description
In July of 1962, an automatic computer-controlled meteorological data acquisition and processing system became operational at Cape Kennedy, Florida. One year of data from this Weather Information Network and Display (WIND) System has been edited. Selected parameters are presented in climatological summaries in this report. (Author).
