Over-water portions of storm tracks before 1944 are subject to considerable uncertainties. Aircraft reconnaissance of storms near critical areas was introduced in 1944, and continuous weather satellite surveillance was introduced in the mid-1960s. These two developments mean that more recent storm records have a higher degree of accuracy than those prior to 1944. No tests for logical consistency have been performed on this data set. |
This data set includes all known Atlantic Basin (Gulf of Mexico, Caribbean Sea, and North Atlantic Ocean) tropical cyclones between 1851 and 2013. The term tropical cyclone as used here refers to subtropical depressions and storms, tropical depressions and storms, and all categories of hurricanes from Category 1 to Category 5. This dataset also includes hybrid systems such as tropical lows, waves, subtropical depressions and storms, as well as extratropical storms. |
GeoPlan relied on the integrity of the attribute information within the original data. |
An ASCII format version of the Historical Atlantic Tropical Cyclone Tracks file is available at <http://www.nhc.noaa.gov/pastall.shtml>. For more information on the Saffir-Simpson Hurricane Scale, please see <http://www.nhc.noaa.gov/aboutsshs.shtml>. For more information on tropical cyclone advisories, please see <http://www.nhc.noaa.gov/HAW2/english/forecast/forecast_products.shtml>. General information on subtropical and tropical cyclones is available from the National Oceanic and Atmospheric Administration, Atlantic Oceanographic and Meteorological Laboratory, Hurricane Research Division FAQ page at <http://www.aoml.noaa.gov/hrd/tcfaq/tcfaqHED.html>, and from the National Hurricane Center Hurricane Basics page at <http://www.nhc.noaa.gov/HAW2/english/basics.shtml>. |
The major constraint in improving scientific understanding of the observed trends and variability of tropical cyclone activity has been a lack of accurate, quality controlled best track data for all tropical cyclone basins globally. |
Over-water portions of storm tracks before 1944 are subject to considerable uncertainties. Aircraft reconnaissance of storms near critical areas was introduced in 1944, and continuous weather satellite surveillance was introduced in the mid-1960s. These two developments allow a high degree of probability that more recent storm center locations were determined with a reasonable degree of accuracy. |

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our webpage at: http://geoplan.ufl.edu/education.html |

Data were obtained from numerous sources. Upon receipt of the electronic files, data were converted to common format (netCDF). Thereafter, numerous merging procedures were implemented, including an assessment of storm position, the identification of unique storms, and an accounting for a variety of storm tracks, storm splits, and storm mergers. An automated algorithm was developed to identify storms tracked by multiple centers by sorting storms in time and space. Any observations at identical times and within 111 kilometers, were identified as identical storms. Once a TC was identified as unique, a storm serial number was created which distinctively numbers the storm. IBTrACS algorithms read all the individual storm tracks from the merged files and create one combined storm track with a single position, wind and pressure every 6 hours (at 00, 06, 12 and 18UTC). Objective automated quality control algorithms were developed and incorporated for the maximum sustained wind and minimum central pressure for each tropical cyclone and time step. These data are in netCDF, with one file per cyclone. Statistics from the merge are also provided (such as number of centers tracking the storm, range in pressure, median wind speed, etc.). Any observations at identical times and within 111 kilometers (approx. 1 degree latitude) were identified as identical storms. In order to create a dataset that was globally homogeneous, the maximum winds are standardize to a single 10-minute averaging period as it is the global standard set by the World Meteorological Organization.
