Attenuation of Melting Ice at C-Band Frequencies, Observed Using Dual-Radar Measurements During the RELAMPAGO Campaign

In this article, the melting ice attenuation in C-band radars is studied. Dual -C-band radar observations from the Remote Sensing of Electrification, Lightning, and Mesoscale/Microscale Processes With Adaptive Ground Observations (RELAMPAGO) campaign are used. Melting ice regions in the radar data are identified using spectral decomposition, Doppler winds, and hydrometeor classification. The attenuation in regions that show polarimetric radar signatures of melting ice is computed using a network-based approach. The network-based approach to computing the parameters for attenuation correction is validated by comparing with disdrometer data over rain. In addition, the attenuation correction parameterization over melting was compared with previous studies.
