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 | Beta |
Updates | To be updated as needed. See revision plans for more information. |
Number of storms | 1233 tropical cyclones |
Number of storm observations | 34,539 netCDF files (Average of 28 observations per storm) |
Temporal coverage | Aug. 12, 1993 to Nov. 20, 2006 |
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.
|
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. |

|
Satellites | F10, F11, F13, F14, F15 |

Data set generation | Hurricane database (HURDAT) and "best track" information (from the JTWC) 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 interpolated position represents the center of the data grid.temporally-interpolated to match the 3-hourly satellite resolution. The satellite data were then interpolated to 8km. NetCDF files also contain the swath data at the native satellite resolution. |
