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 |

| 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. |
