RADAR ELEVATION ANGLE ERRORS AND REFRACTION CORRECTIONS
Abstract
The resuls of the analysis of 474 radar elevation angle measurements are presented. The Fannin-Jehn, Rainey-Thorn, and Bean-Cahoon refraction correction methods are compared. Computed refraction corrections were obtained based in most cases on refractivity profiles determined from rawinsonde observations. Errors in the refraction correction from various sourcesARE DISCUSSED AS IS THE VARIATION OF TOTAL REFRACTION WITH TIME OF DAY AND SEASON. It is concluded that more reliable and time coordinated meteorological data as well as more accuate radar observed angles are needed to study and justify any detailed refraction correction method such as the Fannin-Jehn and the Rainey-Thorn methods.
