NOAA/NCEI Blended Global Sea Surface Winds, Version 2

NBSv2

The NBSv2.0 dataset synthesizes observations from multiple satellites (up to 16 satellites since 1987) to create globally gridded, high-resolution 10 m neutral ocean wind speeds and wind stress components. The wind directions come from two sources depending on the products: for the research delayed mode product, the source is the European Centre for Medium-Range Weather Forecasts ERA5 and for the near-real-time products, the source is the National Centers for Environmental Prediction (NCEP) GFS. This is an updated version of the existing NOAA NBS v1.0, which is a global gridded 0.25 degree and 6-hourly/daily/monthly sea surface winds product that has wide applications in marine transportation, marine ecosystem and fisheries, offshore winds, weather and ocean forecasts, and other areas. A Climatological mean or WMO 30-year Normals are also generated for this product. This newly developed version 2 shows improvement (over its predecessor version 1.0) in following aspects: Resolving very high winds associated with Cyclones/Hurricanes, A gap-free global spatial coverage, Better improved algorithm and coded with open source Python reducing the computational clock time by 10x, and A near-real time production. The data are available in netCDF format for the period of record, July 1987 to present, with six-hourly, daily, and monthly time resolutions for both the blended Sea Surface Wind (SSW) as well as SSW stress data.

Purpose	The hurricane and typhoon storm wind resolving NOAA/NCEI Blended Seawinds version 2.0 (NBSv2.0) contains globally gridded high-resolution 10m ocean neutral winds and wind stresses on a global 0.25 degree grid, and multiple time resolutions of 6-hourly, daily, monthly, and WMO recommended 30-year(1991-2020) climatology. The dataset has great value to the Offshore Wind Energy industries, marine ecosystems such as fisheries (including storminess), and the Ocean Health Indices, and in fact have been called out in NOAA's new Blue Economy plan, as well as the current Administration's initiative on Floating Offshore Wind Energy. Other impacted user communities with past specific examples include marine transportation (e.g. Ship Routing International), marine construction and engineering, ocean modeling and marine forecasts.
