2026-09-28 Aggregated source data for local departures from IRI-2026 and observation-based correction at Hainan Fuke doi:10.57760/sciencedb.013ff en This dataset contains aggregate statistics, figure source values and plotting code supporting the manuscript "Local departures from IRI-2026 and observation-based correction at Hainan Fuke". The observations cover 2014-2020 at Hainan Fuke, China; correction comparisons use 2019 and 2020. IRI-2026 supplies the primary results, while IRI-2020 is included only as an explicitly labelled historical comparison.The single version 1.0.0 ZIP contains six CSV files with 112 aggregate rows, including 78 plotted values for five active figures, together with a data dictionary, metadata, README, licenses, checksums and Python code to redraw the figures. Some values occur in both table and plot sources. The aggregate values are taken from the frozen manuscript results without new fitting or uncertainty estimation.The release supports inspection of reported values and redrawing of figures. It does not contain raw ionograms, GNSS observations, individual manually traced parameters or profiles, observation-level spread-F labels, exact observation times, training records, model weights or internal research logs. It does not support independent model refitting or re-estimation of uncertainty intervals.Aggregate data and documentation are licensed under CC BY 4.0. The plotting code in the code directory is separately licensed under MIT. Dataset creators: Zheng Wang and Jinhui Cai.
