Abstract:
Monthly ocean heat content (OHC) changes (in J/m**2) are provided on a global 0.25 deg grid for the time period 2002-04 till 2024-12. Missing month are due to non-availability of Gravity Recovery and Climate Experiment (GRACE) gravimetry observations and an about one year gap between the GRACE and its successor GRACE-FO missions. The steric expansion of the ocean due to the Earth's energy imbalance can be observed from a combination of GRACE (-FO) satellite gravimetry from ITSG2018 (Mayer-Gürr et al., 2018; Kvas et al., 2019), in situ Argo profiles from easyCORA (Szekely et al., 2019) and along-track satellite altimetry observations from the RADS database (Scharroo et al., 2013). Here we utilized the global fingerprint inversion method (Rietbroek et al., 2016; Uebbing et al., 2019; Uebbing, 2022) in order to derive global and regional sea level budgets. The steric fingerprints and corresponding estimated scaling factors are then utilized to rescale ORAS5 ocean reanalysis (Zuo et al, 2019; Copernicus Climate Change Service, 2021) derived OHC by the ratio of observed and modeled steric sea level as part of the GRACE, Argo and Altimetry based Mode Rescaling (GAAMR) method. This methodology represents an extension to the conventional approach of scaling global steric sea level with one constant factor. The GAAMR method builds on the fingerprint inversion, leveraging the separation into individual sea level modes and enables easy computation of global and regional OHC change.
