N2 - In this paper, we will present results for tropical cyclone wind radii estimation (34-, 50-, 64-knot) using wind speed retrievals from ASCAT-B/C ultra-high-resolution (UHR) processing. ASCAT-UHR derived surface wind radii are compared to storms best tracks obtained from the International Best Track Archive for Climate Stewardship (IBTrACS) dataset. The results were developed using 275 ASCAT-B/C hurricane overpasses from 2022 and 2023, and spans wind speed range from 17-75 m/s. Results show that the root-mean-square-errors (RMSEs) of wind radii from ASCAT-UHR (25.05, 8.75, and 5.52 nautical miles for R34, R50, and R64 respectively) are comparable to the positional uncertainty of IBTrACS.
