Sustained wind speed

NHC's official post-storm best-track data product for Atlantic cyclones from 1851 and Northeast/North Central Pacific cyclones from 1949. Two basin files are delivery partitions of one HURDAT2 product. Records provide native six-hourly and selected asynoptic positions, status, winds, central pressure, wind radii, and landfall/peak identifiers.

Versioned global multi-agency tropical-cyclone best-track collection. NCEI merges recent and historical agency tracks and publishes v04r01 as complete and subset CSV, NetCDF, and shapefile downloads. The product includes best and provisional tracks; release/version identity is v04r01 and the landing page supplies its update schedule. It is not a substitute name for native HURDAT2.

Standing archive of NHC/CPHC advisory forecast track, cone-of-uncertainty and watches/warnings bundles, with related wind-field files, published as downloadable shapefile/KML packages by storm and advisory. This Source preserves forecast-at-issuance evidence and is distinct from final HURDAT2 post-analysis. Geometry remains in source files and is not flattened into speculative scalar Features.

Existing daily station-summary Source derived from ISD observations. Preserve its API and bulk-file access, add exact GSOD scalar fields beyond the existing minimum-temperature and precipitation fields, and clarify that wind is emitted in knots rather than converted mph. Some non-U.S. WMO-contributed data may have commercial-use or re-export restrictions.

Historical reanalysis API at archive-api.open-meteo.com/v1/archive for arbitrary WGS84 points, multiple coordinates, and ISO dates. It publishes gap-filled, model-assisted—not station-only—hourly weather. Available models include global ERA5 from 1940, ERA5-Land from 1950, and ECMWF IFS from 2017. Paid Professional-or-higher access uses the same syntax on reserved customer endpoints and grants commercial use.

Standing automated report product, distinct from WeatherGuidance's manually prepared Forensic reports. A buyer selects any address, latitude/longitude or other location, peril (hail or wind) and search period; reports since 2010 are delivered immediately. Hail reports list events of at least 0.75 inch and maximum sizes at the location and one, two, three and five miles. Wind reports document high-wind history at 50 mph or greater. Histories up to ten years have posted prices and longer periods are offered on request.

Commercial POST /v4/historical API for buyer-selected point, line, or polygon locations, fields, one-hour or one-day timestep, and ISO-8601 start/end times. The archive is a reanalysis product blending forecasts and observations; core worldwide-land fields generally run from 2000-01-01 through seven days before present, with 7–90-day processing latency depending on field. Each call is limited to a 31-day range.

Commercial global Timeline API for buyer-selected addresses, partial addresses, coordinates, or US ZIP codes and date ranges. It returns historical daily and hourly records in JSON/CSV; paid plans document 50+ years of history, commercial use, downloads, API access, and multi-location request allowances.

Commercial version-2.0.1 API returning daily or hourly NOAA-reanalysis history for arbitrary latitude/longitude points, postal codes, DMAs, and OnPoint identifiers. Coverage is every landmass worldwide and up to 200 miles offshore; the public specification does not pin the earliest retained date.

Separately named and separately priced address- or latitude/longitude-specific wind-history PDF product. The current storefront documents wind history from a buyer-selected start date (default 2009) to present, wind speed at the location and within one, three and ten miles, and bulk/enterprise solutions. It does not identify wind as convective or tropical, document observation/model method, expose revision/version pins, or provide a public sample schema.
