ECCO Sea Surface Height: Daily Mean Gridded Data, 1992-2018

1992-01-01 to 2018-01-01 of daily-averaged dynamic sea surface height interpolated to a regular 0.5-degree grid. The data is from the ECCO Version 4 revision 4 ocean and sea-ice state estimate, a dynamically consistent reconstruction produced by NASA. It assimilates observations from multiple satellite altimeters and in-situ programs.

Use Cases

• Modeling global ocean circulation patterns based on dynamic sea surface height.
• Analyzing long-term sea level trends and variability based on the 26-year time series.
• Validating other ocean models or satellite products against the ECCO state estimate.
• Studying ocean-atmosphere interactions using the consistent physical reconstruction.

Strengths

• Covers a 26-year time series from 1992 to 2018.
• Assimilates data from over 10 satellite missions and multiple in-situ observation programs.
• Provides a dynamically and kinematically consistent reconstruction of ocean state.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data ends in 2018; freshness should be verified for current applications.
