Book Description
The radio refractive index can be measured either directly or indirectly. The former method is utilized by radio frequency refractometers; the latter method involves measurement of temperature, pressure and humidity and conversion to refractive index. In terms of convenience and accuracy the direct method is superior; however, lack of the universal use of refractometers requires the use of weather service type of data for the bulk of refractive index structures. Meteorological sensing is limited mainly by the inaccuracy in measuring humidity which under ideal conditions appears to limit the accuracy to 1.0 N. Gradient measurements utilizing radiosondes reflects an accuracy no better than £ 3 N units. Radio frequency refractometers are capable of accuracies as much as an order of magnitude better than that achieved by meteorological sensors. Lightweight refractometers have been devised for balloon-borne and dropsonde measurements reflecting accuracies inferior to the conventional refractometer but superior to the radiosonde.

Book Description
How was it that America would fund its nascent national radio services? Government control and a subscription-like model were both considered! Soon an advertising system emerged, leading radio into its golden age from the 1920s to the early 1960s. This work, divided into two parts, studies the commercialization of network radio during its golden age. The first part covers the general history of radio advertising. The second examines major radio advertisers of the period, with profiles of 24 companies who maintained a strong presence on the airwaves. Appendices provide information on 100 additional advertisers, unusual advertisement formats, and a glossary. The book has notes and a bibliography and is fully indexed.
