Short Summary

The authors present PySHbundle, a Python-based software tool designed to process GRACE gravimetry data into global surface mass change datasets.

Objective

• To provide a Python implementation of the Spherical Harmonics Synthesis (SHbundle) MATLAB codes to facilitate the processing of GRACE gravimetry data.

Study Configuration

• Spatial Scale: Global
• Temporal Scale: Not specified (Software tool)

Methodology and Data

• Models used: PySHbundle (Python implementation of the SHbundle Spherical Harmonics Synthesis)
• Data sources: GRACE (Gravity Recovery and Climate Experiment) gravimetry data

Main Results

• Development and release of PySHbundle (version v0.3.0), a functional Python tool for synthesizing GRACE data into surface mass change datasets.

Contributions

• Increases the accessibility and interoperability of GRACE data processing by migrating the SHbundle functionality from MATLAB to the Python ecosystem, benefiting the geodesy and hydrology research communities.

Funding

• Not specified
