Produced weekly/monthly on a 1° grid. The analysis uses in situ and satellite SST's plus SST's
simulated by sea-ice cover. Before the analysis is computed, the satellite data is adjusted for biases.
The optimum interpolation (OI) sea surface temperature (SST) analysis is produced weekly
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.
Temporal Coverage:
1) Weekly means from 1981/10/29 to 1989/12/28.
2) Weekly means from 1989/12/31 to present.
3) Monthly means from 1981/12 to present
For the more recent period, 1990-present, the weeks are defined to be centered on Wednesday. During the period 1981-1989,
the weeks are centered on Sunday.
