N2 - The NOAA track-wise algorithm, used to infer sea surface wind speed from CyGNSS normalized bistatic radar cross section (NBRCS), is being used in conjunction with v3.0 NBRCS. A performance analysis is provided where NOAA CyGNSS winds derived from v2.1 NBRCS are compared with those derived from v3.0 NBRCS, using available data from August 2018 to November 2020. Additionally, v3.0 and v2.1 NBRCS related timeseries are also compared between each other. The overall standard deviation of the wind speed error, using v3.0 NBRCS, slightly increased from 1.23 m/s to 1.28 m/s. Using v3.0 NBRCS, the overall wind speed bias between NOAA CyGNSS winds and interpolated ECMWF winds, showed a 0.05 m/s decrease overall compared to using v2.1 NBRCS.
