Abstract: PURPOSE: A method for generating total quality index of a weather radar reflectivity data is provided to increase utilization by selecting reflectivity data corresponding to utilization purpose of the radar reflectivity. CONSTITUTION: Topographical echo or anomalous propagation echo, beam shielding, attenuation and error for sampling number for observed radar reflectivity data are quantized to calculate fuzzy quality factor, beam shielding quality factor, attenuation quality factor and sampling error quality factor are calculated (S100). When the beam shielding quality factor or the attenuation quality factor among the calculated individual quality factor are above a pre-established threshold value, a weighting value is multiplied and added to the calculated individual quality factor to calculate total quality index (S200). [Reference numerals] (AA) Start; (BB) End; (S100) Calculate an individual quality factor; (S110) Calculate a fuzzy quality factor; (S120) Calculate a beam shielding quality factor, an attenuation quality factor, and a sampling error quality factor; (S200) Calculate a total quality index
