Hurricane Satellite (HURSAT) Data

The NCDC Hurricane Satellite (HURSAT) AVHRR data set consist of raw satellite observations derived from the AVHRR Level 1B GAC (Global Area Coverage) 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 3350 tropical cyclones
Number of storm observations 130,386 netCDF files
(Average of 39 observations per storm)
Temporal coverage Nov. 5, 1978 to Dec. 15, 2009
Temporal resolution Dependent on number of operational NOAA satellites
Spatial coverage Global coverage
Basins All tropical cyclone-prone basins in the world
Spatial resolutions Data are interpolated to a 4km fixed grid
Data set grid Data from within ~1100 km of the interpolated storm center are provided.
The gridded data are provided at 0.035 deg lat/lon grid centered on the storm location at the time of image on a 601x601 grid.
Spectral coverage All AVHRR channels are provided in the HURSAT files
Satellites NOAA-5 through 18 and METOP-2
Format
  • 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 AVHRR overflights. When AVHRR was nearby, the 6-hourly storm track was interpolated to a position coincident with the AVHRR observation. The satellite data were then interpolated to 4km. NetCDF files also contain the swath data at the native satellite resolution.
