Book Description
Results of an investigation of possible binary digital codes for use in transmitting weather messages are presented. Binary codes in general are discussed, and the nature of symbol translations in the presence of single bit communication facility errors is indicated. Also investigated was the variation in symbol occurrence between normal and weather-message English. Symbol probability-of-occurrence data are used to establish code evaluation criteria and to describe the derivation of an optimum code through computer solution. code indicating an improvement of ten times over Modified Baudot Code, is presented. However, because of the implications involved in possible optimum code instrumentation, this study was limited in scope to codes that could be instrumented with only minor modification to existing facilities.

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
A short review is given of the literature pertinent to the bolometric correction. A recommended scale of bolometric corrections is presented based upon recent model atmospheres for stars of early spectral type, and upon stellar energy distributions synthesized from photoelectric observations of stars later than FO V. The reduction of various photoelectrically determined magnitude and color systems to a common system and the further reduction of these measurements to absolute energy units is discussed in some detail.
