Abstract:

Any changes to the Earth’s climate system affect an imbalance of the Earth’s energy budget due to natural or human made climate forcing. Improving the accuracy of our estimates of Earth’s climate state and variability is critical for advancing our understanding and prediction of the evolution of our climate. Variations in the world’s ocean heat storage and its associated volume changes are a key factor to gauge global warming, to assess changes in the Earth’s energy budget and to estimate contributions to the global sea level budget. Observations during the era of Argo have a high potential to deliver accurate data to be used for such analyses. Moreover, consistency checks through physical budget constraints with the combined use of climate observations (in situ, remote sensing) and tools (reanalysis, models) have a large potential to deliver a robust uncertainty assessment and to shed new light on unresolved climate science issues – the principal objective of the CLIVAR research focus CONCEPT-HEAT. This talk will give an overview on the development of ocean climate indicators, and their use for physical budget constraints. Specific examples will be introduced, main outcomes and challenges are discussed and an overview on CONCEPT-HEAT activities is given.
