2026-08-18 Derived data supporting a triangulated quality assessment of the 2015-2020 Danzhou/Fuke multi-GNSS TEC archive doi:10.57760/sciencedb.00zl6 en This dataset provides the analysis-level products and reproducible workflow supporting a triangulated quality assessment of the official absolute total electron content (ATEC) archive from the Chinese Meridian 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. Raw Meridian Project, global ionospheric map, ionosonde, and OMNI source archives are not redistributed; their authoritative identifiers and access routes are documented in the deposit. total electron content; multi-GNSS; ionosphere; data quality; low-latitude ionosphere; Chinese Meridian Project; Danzhou Station; Fuke Station Zheng Wang Yusen Tian Kai Ding PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
