Tropospheric Fields and Their Long-Term Variability as Reported by TASO

This report presents data from long-term recordings of radio field strength over a large number of propagation paths, and presents curves for predicting field strength over a smooth earth for frequencies between 40 megacycles and 1000 megacycles per second. The basic data provided for the Television Allocations Study Organization during 1957 and 1958 include recordings made in several parts of the world and over various types of terrain and were supplied by numerous sources.
