Derived data supporting a triangulated quality assessment of the 2015-2020 Danzhou/Fuke multi-GNSS TEC archive

Project

Phase I GNSS TEC monitor (GPStation6) at Danzhou Station, formerly Fuke Station, Hainan, China, for 23 September 2015 to 31 December 2020. The deposit contains derived analysis tables, figure source data, registered evidence and claim tables, executed configurations, verification records, software-environment information, and Python analysis and test code.Data quality is evaluated through five complementary branches: internal multisatellite consistency; GPS-BDS constellation consistency; agreement with IGS, CODE, JPL, and ESA global ionospheric maps; exact-time comparison with expert-checked DPS-4D ionosonde TEC; and use-specific coverage assessment for climatological, spatial, and storm-event studies.The deposited evidence supports scientific use of the official ATEC product when geometry-, ionospheric-state-, and purpose-specific uncertainty and coverage conditions are retained.
