title = "NOAA CYGNSS Wind Product: Recent Progress",
abstract = "The current version of the NOAA CyGNSS wind product has three issues which hinder its overall performance: a 13\% loss in global coverage due to the exclusion of roll angle data (greater than | 5o |), a tendency to underestimate in the higher wind regime, and the presence of outliers. The proposed improvements are first the use of a point-wise σo bias threshold to address the roll angle data, the use of a cumulative distribution function matching technique to help CyGNSS high wind performance, and an update to the quality flag to significantly decrease the presence of outliers. The implementation of these improvements enables global coverage to increase by 12.56\%, a decrease in overall bias in the higher wind regime between NOAA CyGNSS winds and HWRF from -0.44 to -0.14 m/s, and a drastic decrease in outliers.",
