- Global Tropical Cyclone "Best Track" Position and Intensity Data
Time series of tropical cyclone "best track" position and intensity
data are provided for all ocean basins where tropical cyclones
occur. Position and intensity data are available at 6-hourly
intervals over the duration of each cyclone's life. The general
period of record begins in 1851, but this varies by ocean basin. See
the inventories [http://rda.ucar.edu/datasets/ds824.1/inventories/]
for data availability specific to each basin.
This data set was received as a revision to an NCDC tropical cyclone
data set, with data generally available through the late 1990s.
Since then, the set is being continually updated from the U.S. NOAA
National Hurricane Center and the U.S. Navy Joint Typhoon Warning
Center best track archives. For a complete history of updates for
each ocean basin, see the dataset documentation
