Global Navigation Satellite System Reflectometry (GNSS-R)-based wind retrieval techniques use the global positioning system (GPS) signals scattered from the ocean surface in the forward direction, and can potentially work in all weather conditions. A

A novel approach in addressing cyclone global navigation satellite system (CyGNSS) intersatellite and GPS-related calibration issues is proposed, based on a track-wise $σ^o$ bias correction method. This method makes use of both ancillary data from n

Hurricane Dorian was the first major hurricane of the 2019 Atlantic season. Dorian formed on August 24, from a tropical wave in the Central Atlantic. Over next several days it gradually strengthened and become a hurricane on August 28th. Dorian rapid
