Azimuthal Dependence of CYGNSS Winds in Tropical Cyclones

This article investigates the performance of a new CYGNSS wind speed product dedicated for tropical cyclones named merged (MRG). First, it analyzes the azimuthal performance. Later, the impact of the swells left after by the cyclone is also analyzed. The reference winds are those from another new product named MAXSS, a multi-mission product that blends winds from different sensors. Results show a dependency of the MRG winds on the two analyzed parameters, paving the way for an eventual incorporation of them into the retrieval algorithm.
