Geodetic Contributions to Sea Level Budget

What is Geodetic Contributions to Sea Level Budget?

Geodetic Contributions to Sea Level Budget integrate satellite gravimetry (GRACE/GRACE-FO), altimetry, and GPS observations to partition global mean sea level rise into steric and mass components.

This subtopic combines GRACE mass change data with altimetry-measured sea level and GPS vertical land motion to close the sea level budget. Key efforts address GRACE-FO continuity and reference frame improvements like ITRF2008 (Altamimi et al., 2011, 1163 citations). Over 10 papers from the list, including Cazenave (2018, 588 citations), quantify budget closure since 1993.

Key Challenges

Why It Matters

Geodetic partitioning resolves steric-mass imbalances in sea level rise, essential for IPCC projections of 20th-21st century trends (Church and White, 2011, 1588 citations). It quantifies ice sheet contributions from Greenland and Antarctica using GRACE/GRACE-FO continuity (Velicogna et al., 2020, 311 citations). Applications include glacial isostatic adjustment modeling for relative sea level histories (Argus et al., 2014, 548 citations) and global gravity models like EIGEN-6C4 (Förste et al., 2014, 453 citations).

Key Research Challenges

GRACE-FO Data Continuity

Extending GRACE mass records into GRACE-FO requires handling instrument gaps and performance shifts (Landerer et al., 2020, 691 citations). Calibration ensures seamless ice mass loss trends over Greenland and Antarctica (Velicogna et al., 2020, 311 citations).

Reference Frame Errors

ITRF realizations like ITRF2008 impact vertical velocities in sea level budgets (Altamimi et al., 2011, 1163 citations). Systematic errors propagate into postglacial rebound models (Argus et al., 2014, 548 citations).

Budget Closure Discrepancies

Global sea level budgets from 1993-present show steric-mass imbalances (Cazenave, 2018, 588 citations). Altimetry-gravity synthesis reveals unmodeled components (Cazenave and Nerem, 2004, 553 citations).
