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 <b>data.zip</b> 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 <b>Code.zip</b> 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.<br>
