HURSAT- Hurricane Satellite 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	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. Swath - Native satellite swaths (resolution varies from ~15km to 70km) Gridded - Interpolated to 8km (to match HURSAT-B1)
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	F10, F11, F13, F14, F15
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	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.
