Sea-level components, 2002-2022

This repository contains regional monthly time series of total (alt), sterodynamic (sdsl) from 1993-2022 and mass-driven sea-level change from 2002-2022. Total sea-level chnage is obtained from altimetry product from JPL MEaSUREs Gridded Sea Surface Height Anomalies Version 2205, which was regridded to 1x1 degree. In addition to the altimetry sea-level anomaly (sla), which is absolute sea-level, we also provide SLA in relative sea-level (RSL), which has been computed by applying a GIA and ocean bottom deformation corrections (sla_noGIA_noOBP). Sterodynamic sea-level change is computed from GREP reanalysis by combining steric sea-level, calculated from temperature and salinity, with ocean dynamic sea level, calculated from reanalysis SSH. For details on the methodology read Camargo et al (2023) https://os.copernicus.org/articles/19/17/2023/os-19-17-2023.html, in specific the Appendix. The mass driven is computed with mass changes from GRACE satellite over land (JPL mascons), which are then used as input in the sea-level equation. This time series is updated from Camargo et al (2022) https://esd.copernicus.org/articles/13/1351/2022/esd-13-1351-2022.html.
