Auxiliary and validation data for SAGEA-fluid

SAGEA-fluid is an open-source Python-based solver designed to evaluate the self-attraction and loading effect (SAL), geocenter motion (GCM), and Earth orientation parameters (EOPs) including polar motion (PM) and length-of-day (LOD) variations induced by surface fluid redistribution. Building upon the core framework and data post-processing capabilities of SAGEA, SAGEA-fluid supports the integration of multi-source surface fluid datasets for geophysical effect estimation. This enables users, including those without extensive background knowledge in geodesy, to independently investigate and interpret surface fluid processes.The file data.zip provides auxiliary and validation datasets required to run the demonstration scripts included in SAGEA-fluid. These datasets facilitate immediate testing and replication of typical processing demos. Users should extract the contents of "data.zip" into the directory "./SAGEA-fluid/data/" to ensure that the demonstration programs can be executed successfully.The accompanying file Code.zip contains the initial release version of SAGEA-fluid, updated to November 2025. For the most recent version and ongoing updates, users are encouraged to refer to the project repository at https://github.com/NCSGgroup/SAGEfA-fluid.
