Abstract

In November 2019, the Ocean Surface Winds Team at NOAA-NESDIS-STAR released to the public their first version of sea surface winds for the Cyclone Global Navigation Satellite System (v1.0). The reported winds are provided on a 25km grid along each track. A boxcar averaging step is included in order to remove unwanted noise in the signal. Calibration issues are greatly reduced by the use of a track-wise bias correction applied to the normalized bi-static radar cross section. The wind speed is then retrieved on a track-by-track basis where both daily global and storm centered images are provided to the public at https://manati.star.nesdis.noaa.gov/datasets/CYGNSSData.php. For in-depth analyses, NetCDF files are also made available (access instruction provided on the aforementioned link). A comparison with collocated NOAA ASCAT A/B 25km wind product, between July and October 2018, resulted in a -0.13 m/s bias and a 1.23 m/s standard deviation.
