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|
|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.|
