Hourly Atlantic hurricane data

In the absence of higher temporally resolved information on historical hurricanes, we develop a set of hourly-interpolated track values that can be used for hurricane climate studies. A spline interpolation is used to obtain locations and wind speeds at 1-hr intervals from the 6-hr values for all tropical cyclones in NOAA's dataset. The data set is augmented with a set of storm intensification and heading estimates based on a Savitzky-Golay filter. The data are available here.
