NOAA CDR OISST: Optimum Interpolation Sea Surface Temperature (NOAA/CDR/OISST/V2)
Version V2
The NOAA 1/4 degree daily Optimum Interpolation Sea Surface Temperature
(OISST) provides complete ocean temperature fields constructed by combining
bias-adjusted observations from different platforms (satellite, ships,
buoys) on a regular global grid, with gaps filled in by interpolation.
Satellite data from the Advanced Very High Resolution Radiometer (AVHRR)
provides the main input which permits the high temporal-spatial coverage
beginning in late 1981 to the present.
The OISST dataset has a single day’s data processed twice. First a near
real-time preliminary version is released with a lag of 1 day, and a final
version with a lag of 14 days. The final version uses extra days for
smoothing, and zonal bias correction in addition to replacing the
preliminary version.
