Measuring and understanding Earth Energy Imbalance (EEI), its time variability, and long-term trend is essential to understanding the current state of our planet and predicting its future evolution. Under its Data and Analysis Panel (GDAP), the World Climate Research Programme’s (WCRP) core project Global Energy and Water Exchanges (GEWEX) initiated the “Earth Energy Imbalance assessment”.
The GEWEX-EEI assessment’s objective is to evaluate the quality and the uncertainty of current EEI estimates. It focuses mainly on two sources of data:
1) observations of the TOA radiative fluxes from space radiometry, and
2) observations of the ocean heat content from in situ data, satellite altimetry, space gravimetry and ocean reanalysis.
The approach adopted in the GEWEX-EEI assessment is to design an intercomparison of EEI estimates and associated uncertainty. This intercomparison enables progress on:
Main Goals for this workshop:
EEI assessment Workshop Themes include:
Theme 1: Science of Earth’s Energy Imbalance

Theme 3: Earth radiation at the TOA, surface and in the atmosphere
Theme 4: Earth’s heat inventory – deep ocean, land, atmosphere and cryosphere
Theme 5: Energy and Water Cycle Linkages and their impact on EEI
Theme 6: Future Ocean, ERB & EEI Observing Systems
