RMS HWind is the world's leading provider of tropical cyclone wind field data, with observation-based data products for both real-time and historical wind field analyses in the western North Atlantic, Eastern Pacific and Central Pacific basins.
Comprehensive and Reliable Hurricane Surface Wind Analysis
Developed over 20+ years by world-leading hurricane observation researchers, HWind datasets are considered to be the industry standard "ground truth" for tropical cyclone wind assessment before, during, and following landfall.
HWind products are used by (re)insurers, risk modelers, academia, and government agencies for a variety of commercial and scientific purposes, such as real-time event preparation and response, post-event loss assessment, and model validation against past loss experience.
Backed by hundreds of citations in peer-reviewed publications across a variety of research fields, HWind data is used by researchers and scientists for numerous applications, including numerical weather prediction model validation, calibration of wind remote sensing systern measurements, and as inputs for storm surge and wave models.
Unrivalled Insight and Detail
HWind products reflect wind field characteristics with more accu-racy, precision, and frequency than publically available sources, including the National Hurricane Center.
HWind datasets incorporate unique wind field analysis metrics de-veloped by HWind scientists, such as Integrated Kinetic Energy, a globally recognized index for measuring tropical cyclone size and intensity, and a proven alternative to the Saffir-Simpson Scale.
Unparalleled Suite of Observational Data Sources
HWind incorporates the most comprehensive set of observational data sources In the market, spanning more than thirty land, air, and sea-based platforms including aircraft reconnaissance, dropsondes, airborne Doppler radar wind measurements, buoys, satellites, and coastal observation networks.
HWind Legacy Archive
RMS hosts a publicly-available legacy version of HWind archive data, which contains products from historical events through 2013, developed while HWind was a public entity under the National Oceanic and Atmospheric Administration. For more information on how to access this data, please click here.
