Description
NASA’s Space Physics Data Facility (SPDF https://spdf.gsfc.nasa.gov) is the active and final archive for space physics data from NASA missions and joint missions with other national or international agencies. The data covers the space from 10 solar radii to the local interstellar medium (about 160 astronomical units), and the magnetosphere - ionosphere - thermosphere - mesosphere (M-ITM) of Earth and other applicable planets. SPDF serves the global science community with open access to about 800 TB of space physics data to enable correlative and collaborative research across discipline and mission boundaries with more than 100 operating and past missions/projects. Besides updating the self-describing Common Data Format (CDF) and the International Solar-Terrestrial Physics (ISTP) metadata guidelines, SPDF has been improving three main science-enabling services: Coordinated Data Analysis Web (CDAWeb), Satellite Situation Center Web (SSCWeb), and OMNI Web. In this annual report, we report the latest status of data archiving at SPDF and copying the data into HelioCloud for cloud-based collaborative data analysis. We highlight some new features and tools of SPDF, including the improved browser-based 4-D orbit viewer with simulated time-dependent bow shock and magnetopause, the improved browser-based ISTP metadata editor, a new solar energetic particle portal and propagation tool, a new capability of responding to queries using Large Language Models (LLMs) and Model Context Protocol (MCP). These updates facilitate the production, access, analysis, and citation of space physics data and other digit resources, therefore ultimately support Open Science and enhance the productivity for the science community.
