International Best Track Archive for Climate Stewardship (IBTrACS) Project, Version 4

Metadata Updated: November 12, 2020

The International Best Track Archive for Climate Stewardship (IBTrACS) provides location and intensity for global tropical cyclones. The data span from the 1840s to present, generally providing data at 3-hour intervals. While the best track data is focused on position and intensity (maximum sustained wind speed or minimum central pressure), other parameters are provided by some agencies (e.g., radius of maximum winds, environmental pressure, radius of hurricane force winds, etc.) and are likewise provided in IBTrACS. Files are available subset by Basin or time period, where basins include: East Pacific, North Atlantic, North Indian, South Atlantic, South Indian, South Pacific, and the West Pacific. Time periods include: All data, since 1980, and the last 3 years.

Licence The primary limitation is that information is limited to known tropical systems. So those not observed are not recorded (this is much more prevalent prior to satellite observations). Another limitation is that various agencies have different practices when it comes to reporting maximum sustained wind speeds. This makes comparing winds between basins or through time problematic because changes in agencies, personnel or practices can mask underlying climatological shifts (and vice versa).
