This document analyzes the polarimetric characteristics of mesoscale cellular convection (MCC) seen in Synthetic Aperture Radar (SAR) images over the ocean and how they differ from characteristics of the open ocean surface. MCC areas showed higher values of co-polarization phase difference, entropy (H), and alpha angle (α) compared to typical ocean surface values. The document presents datasets used, Weather Research and Forecasting (WRF) model results confirming signals were MCC, and concludes polarimetric parameters have potential to identify atmospheric convection from open ocean SAR images.
