Hurricane Satellite (HURSAT) Data

The NCDC Hurricane Satellite (HURSAT) Microwave data set consist of raw satellite observations derived from the SSMI Sensor Data Records (SDR) data centered on historical tropical cyclones (TC).

Current Data Set Version v05
Updates To be updated as needed. See revision plans for more information.
Number of storms 2412 tropical cyclones
Number of storm observations 58,284 netCDF files
(Average of 24 observations per storm)
Temporal coverage July 10, 1987 to Dec. 14, 2009
Temporal resolution Dependent on number of operational SSMI
Spatial coverage Global coverage
Basins All tropical cyclone-prone basins in the world
Spatial resolutions Data are provided in two forms: gridded and swath.
  • Swath - Native satellite swaths (resolution varies from ~15km to 70km)
  • Gridded - Interpolated to 8km (to match HURSAT-B1 resolution)
Data set grid Data from within ~1100 km of the interpolated storm center are provided.
The gridded data are provided at 0.07 deg lat/lon grid centered on the storm location at the time of image on a 301x301 grid.
Spectral coverage
  • 19 GHz (Vertical & Horizontally polarized)
  • 22 GHz (Vertically polarized)
  • 37 GHz (Vertical & Horizontally polarized)
  • 85 GHz (Vertical & Horizontally polarized)
Satellites F8, F10, F11, F13, F14, F15
  • non-gonvernment domain netCDF
  • Each netCDF file is a snapshot of the storm from one of the satellites.
  • Multiple netCDF files are possible when a storm is visible by two satellites at the same time.
Data set generation IBTrACS v03r02 were used to locate potential SSMI overflights. When SSMI was nearby, the 6-hourly storm track was interpolated to a position coincident with the SSMI observation. The satellite data were then interpolated to 8km. NetCDF files also contain the swath data at the native satellite resolution.
