Microwave Effective Earth Radius Factor Variability at Wiesbaden and Balboa.
Abstract
This report describes the variability of the microwave (3 to 30 GHz) circuit design parameter, effective earth radius factor, at two sites which served as test cases: Balboa, Panama, and Wiesbaden, Germany. Median effective earth radius factors, K, derived from meteorological data for the first 100 m altitude at these two sites, were 1.32 for Wiesbaden and 1.68 for Balboa. Median K factors for 84 other world localities are included in table 1. Numerous medians differ considerably from the K = 4/3 standard. K factor variability at Balboa and Wiesbaden is illustrated with sets of equivalent earth profile curves enclosing 68.3, 95.4, 99.7, and 100 percent of the data and by K factor cumulative distribution functions bounded by respective 90 and 99 percent confidence limits. Effective earth radius factors were highly variable, particularly at Balboa, where the meteorological variability is high within the first 100 m altitude. (Author)
