Source: This accession contains the gridded 5-day mean sea surface height
anomaly (SSHA) and Ku Band significant waveheight (SWH-KU) observed from
Jason-1 and OSTM/Jason-2 satellites. This dataset has been generated in
near-real time during the Deepwater Horizon Oil Spill Event in order to
provide users a quick view on the sea level change and wave activity in the
Gulf of Mexico though it is under a global coverage. All the observations in
5 days are averaged and interpolated into 0.25 longitude degree and 
0.25 latitude degree grid.

The OSTM/Jason-2 observations are picked from Interim Geophysical Data Records
(IGDR) which is archived under NODC AMS accession 0043269.
(http://www.nodc.noaa.gov/cgi-bin/search/prod/accessionsView.pl/details/43269)

The Jason-1 satellite IGDR data are selected from PO.DAAC, JPL/NASA at
ftp://podaac.jpl.nasa.gov/pub/sea_surface_height/jason/igdr_ssha_netcdf/data/.

Above original data have been processed, gridded, visualized and converted 
into NetCDF format by scientists in NODC's satellite oceanography group.
