Brief description
Monthly standard deviation of sea surface height (in metres) estimated on a 0.2 x 0.2 degree grid for the region: 90E-180E, 60S-0. Data used in making the estimates are the gridded maps of height for 1993-2001 based on tide gauge and altimeter observations. The gridded fields are created using optimal interpolation and the grid scale is smaller than the largest gaps between satellite tracks so fine scale O(50km) height gradients in the ocean are often missed. For most of the time data were only available from two satellites and at times only one.Lineage

Statement: The dataset was extracted from hindcast height maps described in BLUELink hindcast. The gridded fields are created using optimal interpolation and the grid scale is smaller than the largest gaps between satellite tracks so fine scale O(50km) height gradients in the ocean are often missed. Altimeters used in the analysis are Topex/Poseidon, Jason-1, ERS-1, and ERS-2. The method of optimal interpolation has been verified against surface drifting buoys and is qualitatively verified with SST observations.
Data time period: 1993 to 2001
