| hasSummary |
-
The NOAA National Center for Environmental Prediction (NCEP)
optimum interpolation (OI) sea surface temperature (SST) analysis is
produced weekly and monthly on a one-degree grid. The analysis uses
in situ and satellite SSTs plus SSTs simulated by sea ice cover.
Before the analysis is computed, the satellite data is adjusted for
biases using the method of Reynolds (1988) and Reynolds and Marsico
(1993). A description of the OI analysis can be found in Reynolds
and Smith (1994). The bias correction improves the large scale
accuracy of the OI.
In November 2001, the OI fields were recomputed for late 1981
onward. The new version will be referred to as OI Version 2, and the
most significant change is the improved simulation of SST from sea
ice data following a technique developed at the UK Met Office. This
change has reduced biases in the OI SST at higher latitudes. Also,
the update and extension of COADS has provided us with improved ship
data coverage through 1997, reducing the residual satellite biases
in otherwise data sparse regions. For more details, see Reynolds, et
al. (2002).
