Ocean heat content (OHC) and earth energy imbalance (EEI)

The Ocean Heat Content ("OHC") is estimated from the measurement of the thermal expansion of the ocean based on differences between the total sea-level content derived from altimetry measurements and the mass content derived from gravimetry data, noted “altimetry-gravimetry”.

The Earth Energy Imbalance ("EEI") indicator is derived from the temporal variations of the ocean heat content, i.e. by calculating its derivative (called the ocean heat uptake).

A single NetCDF file provides all variables, including all data used to calculate the Ocean Heat Content and the Earth Energy Imbalance indicators, delivered transparently and allowing users to reconstruct their own Ocean Heat Content or Earth Energy Imbalance indicators. Users will therefore be able to find, among other things :

- the regional map of the Ocean Heat Content trends (3°x3°) (see image associated with this metadata sheet)

- global ocean heat content time series (representative of the globe within the extent of data availability)

- earth energy imbalance time series (from global OHC filtered-out from signals lower than 3 years)
