To compensate radar reflectivity for attenuation effect, a new method for attenuation correction of the radar reflectivity using\narbitrary oriented microwave link (referred henceforth to as ACML) is developed and evaluated. Referring to the measurement of\narbitrary orientedmicrowave link, the ACML method optimizes the ratio of specific attenuation to specific differential phase which\nis a key parameter in attenuation correction schemes. The proposed method was evaluated using real data of a dual-polarization\nX-band radar and measurements of two microwave links during two rainstorm events. The results showed that the variation range\nof the optimized ratio was overall consistent with the results of the previous studies. After attenuation correction with the optimal\nratios, the radar reflectivity was significantly compensated, especially at long distances. The corrected reflectivity was more intense\nthan the reflectivity corrected by the ââ?¬Å?self-consistentââ?¬Â (SC) method and closer to the reflectivity of a nearby S-band radar. The\neffectiveness of the method was also verified by comparing the rain rates estimated by the X-band radar with those derived by rain\ngauges. It is demonstrated that arbitrary oriented microwave link can be adopted to optimize the attenuation correction of radar\nreflectivity.
