NOAA OI Sea Surface Temperature and Climatology

This dataset provides global gridded sea surface temperature (SST) data derived from NOAA's Optimum Interpolation version 2 (OIv2) analysis. It includes weekly and monthly SST values, a long-term monthly climatology for 1971-2000, and weekly normalized error variance fields on a 1-degree grid. The data is part of the ISLSCP II collection and has been processed with a specific land/water mask.

Use Cases

• Analyzing weekly global SST anomalies using the provided weekly SST and error variance fields.
• Establishing a baseline climate state by comparing current SST readings against the 1971-2000 monthly climatology.
• Validating ocean-atmosphere coupling in general circulation models using the gridded, masked SST data.

Strengths

• Data integrates multiple observation types, including seven days of in-situ (ship/buoy) and satellite data, plus sea ice concentration.
• Includes a long-term 30-year monthly climatology (1971-2000) for robust baseline comparisons.
• Provides associated uncertainty metrics through weekly normalized error variance fields.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided by any source.
• Sources conflict on the last updated date, with one listing 2000-12-31 and others listing 2026-03-13.
