Understanding Sea Level
Key Indicators
Steric Height
Global thermosteric height changes computed from the gridded temperature and salinity files by National Centers for Environmental Information at the National Oceanic and Atmospheric Administration (https://www.ncei.noaa.gov/access/global-ocean-heat-content/fsl_global.html). This is an indicator for how the changing ocean heat content changes the sea surface height over time.
Steric height was computed from these data between the surface and 2000 m.
Data shown are latest available, given time needed to allow for processing.
