Abstract : This paper describes the acquisition and analysis of azimuthal noise data collected at the Bondville Road Field Station. Noise levels in 12 directions were measured for ten one-day periods. The data were collected in four - minute samples at hourly intervals, at frequencies of 5, 10, and 15 MHz. The details of a similar basic data-collection scheme are outlined by A. Weeks. The experimental configuration used for the collection of the data presented here is in Appendix A. (Author)
