GSM monthly fields
Read CSR/JPL/GFZ spherical harmonics and build the available time index.
Satellite gravity processing notes
From monthly spherical harmonics to gridded equivalent water height products, with reproducible configuration, filter traces, and validation notes.
This blog records practical decisions behind a GRACE/GRACE-FO Level-2 workspace: MATLAB and Python runtimes, JSON-driven processing, filter-product comparisons, and output checks for EWH stacks.
Pipeline
Read CSR/JPL/GFZ spherical harmonics and build the available time index.
Apply low-degree replacement, optional GIA, and mean-field removal.
Generate RAW, P4M6, GAUSS, FAN, DDK4, and HSAF from one corrected source.
Synthesize EWH grids as [nLon x nLat x Nt] and write monthly products.
Workbench
The desktop workflow keeps data paths, scientific parameters, runtime status, and preview checks close together, so each product can be traced back to the same configuration source.
Blog focus
P4M6_GAUSS as the conservative baseline, with DDK4 and HSAF kept for comparison.
Stored EWH products follow the pipeline unit contract, with preview conversion documented separately.
Local Python GUI, MATLAB one-click runs, and SLURM/HPC jobs share the same JSON configuration.
