Abstract : Meteorological data has been processed to investigate RF propagation efforts of the tropospheric region from ground to 28 KM in space. A data base has been developed to provide enough information for analyzing many different phenomena of the troposphere in terms of lapse rate, refractivity, range error, angle error, slant range, and interrelationships among these parameters. Based on preliminary analysis, the results are very distinguishable from the values arrived at through the application of conventional data for analysis of RF propagation patterns. This implies that the seasonal average value provides better indications of the current atmospheric variation than the annual global average value which most users have adopted for convenience. (AN)
