HYCOM: Hybrid Coordinate Ocean Model, Sea Surface Elevation [deprecated]

AI-generated Key Takeaways

• This HYCOM dataset has been superseded by a newer version focused on sea surface elevation and is considered deprecated.

• It provides sea surface elevation anomaly data from 1992 to 2018, interpolated to a 0.08 degree grid.

• The data is freely available for use without restrictions and is sourced from the Hybrid Coordinate Ocean Model (HYCOM).

• HYCOM is a data-assimilative ocean model incorporating salinity, temperature, velocity, and elevation variables.

• This dataset is hosted on Google Earth Engine and is easily accessible for analysis and visualization.

Caution: This dataset has been superseded by HYCOM/sea_surface_elevation.

Description

The Hybrid Coordinate Ocean Model (HYCOM) is a data-assimilative hybrid isopycnal-sigma-pressure (generalized) coordinate ocean model. The subset of HYCOM data hosted in EE contains the variables salinity, temperature, velocity, and elevation. They have been interpolated to a uniform 0.08 degree lat/long grid between 80.48°S and 80.48°N. The salinity, temperature, and velocity variables have been interpolated to 40 standard z-levels.

The HYCOM Consortium, which includes the National Ocean Partnership Program (NOPP), is part of the U.S. Global Ocean Data Assimilation Experiment (GODAE).

Funded by the National Ocean Partnership Program, the Office of Naval Research (ONR), and DoD High Performance Computing Modernization Program.
