GRACE Regression Analysis: Arctic Glacier Mass and Climate Indices, 2002-2024

Monthly North Atlantic Oscillation and Pacific Decadal Oscillation index time series alongside regional glacier mass-anomaly data derived from three GRACE/GRACE-FO mascon solutions. The dataset spans from April 2002 to October 2024 and was created by Xiaojun Ma to support reproducibility of analyses linking Arctic glacier mass variability to large-scale climate modes. Regional glacier mass time series were extracted for Randolph Glacier Inventory version 7.0 regions using JPL, CSR, and GSFC mascon products resampled to a common 0.5° grid.

Use Cases

• Estimate regional glacier mass-balance trends based on the provided GRACE/GRACE-FO mascon solutions.
• Compare glacier mass-anomaly results among the JPL, CSR, and GSFC mascon products.
• Perform regression analyses using cumulative NAO and PDO indices to explain glacier mass variability.
• Conduct independent component analysis on the gridded masked time series of glacier mass anomalies.

Strengths

• Includes data from three independent GRACE/GRACE-FO mascon solutions (JPL, CSR, GSFC) for cross-comparison.
• Covers a time span of over 22 years, from April 2002 to October 2024.
• Regional glacier masks are based on the Randolph Glacier Inventory version 7.0 with a 1° buffer to reduce signal truncation.
• Data is provided in both centimetres of equivalent water height (gridded) and gigatonnes (integrated).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Missing GRACE/GRACE-FO months, including the inter-mission gap, are represented by NaN values.
