Abstract
A method for monitoring a real-time calibration bias in radar reflectivity includes monitoring a radar reflectivity change by calculating a relative bias of reflectivity based on the change in reflectivity to ground echo reflectivity of a specific time, estimating calibration bias in reflectivity from the relative bias of reflectivity and a differential phase based on self-consistency between dual-polarimetric variables during a rainfall period, verifying the calibration bias in reflectivity by calculating a reflectivity mean bias through comparison of reflectivity of an overlapping area between two adjacent radars in a radar observation network by applying the estimated calibration bias to each of the two adjacent radars, and recalculating the calibration bias in reflectivity when the reflectivity mean bias between the two adjacent radars is larger than a first threshold. Accordingly, it is possible to provide the calibrated reflectivity data in real-time.
