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. Users: reinsurance, forecasters, media, emergency managers, climate monitoring, etc. Use cases: To understand the distribution, frequency and intensity of tropical cyclones. The primary benefit of this dataset is the inclusion of many sources of tropical cyclone data in one place.

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). otherRestrictions Cite as: Gahtan, Jennifer; Knapp, Kenneth R.; Schreck, Carl J.

The data are produced from real time (during the season) and post-season analysis of TC observations. Thus, there is some uncertainty on what observations were available at a given agency, what practices were in place that might affect intensity estimates and what practices and procedural thresholds were used to track some systems but not others. Reformat source data to netCDF This step reformats all best track files into a uniform netCDF dataset structure. This simplifies further processing. processor Identify similar storms and merge data. The agencies each have different practices for storm identification. Thus, it takes some analysis to determine which tracks from one agency correspond tracks in another. DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce processor Produce track data for individual storms Once storms as identified as potentially the same, then analysis is performed to define tracks and output all data into intermediate netCDF files. DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce processor Reformat track data by basin and date. Many customers need on subsets of IBTrACS. Tracks are split by basin (e.g., North Atlantic, Eastern Pacific, Western Pacific, North Indian, South Indian and South Pacific) or by time period (all years, ears since 1980 or last 3 years). The result are file sets in 3 formats: CSV, shapefile and netCDF.
