Short summary
Monthly maps of steric sea level, thermometric sea level, and ocean heat content anomalies from January 2003 through December 2023 are described. The maps were created from a statistical combination of satellite altimetry, satellite gravimetry, and in situ Argo profiles of temperature/salinity to 2000 m depth. Data are mapped at long wavelengths to reduce contamination from mesoscale eddies. The data are intended for the study of sea level budgets and changes in ocean heat uptake.
