Aggregate results for sporadic E conditions associated with four spread F morphologies over Hainan
Listed in ScienceDB
This dataset contains aggregate results supporting the study "Sporadic E conditions associated with four spread F morphologies over Hainan: local-time-adjusted and seasonal comparisons".
Description
The study compares E and sporadic E measurement probabilities and measured parameters among range, strong range, frequency and mixed spread F at Hainan Fuke (19.5 degrees N, 109.1 degrees E) during 2014-2020. The archive includes group-level estimates and uncertainty intervals, seasonal and summer-autumn comparisons, non-spread-F reference coverage and sampling summaries, source data for three figures, plotting code and analysis source.
Frequencies are expressed in MHz and Es virtual height in km. Results are adjusted for the usual temporal background, with supplementary grouped resampling and paired background refitting.Source observations are associated with the Chinese Meridian Project ionosonde product for Danzhou (10.12176/01.06.00508-V01). Guojun Wang and Zheng Wang manually reviewed ionograms and revised traces; parameters were calculated and exported after revision using ARTIST 5002 and SAO Explorer 3.4.17.

SF labels were inferred with the same classification algorithm throughout the study. Only statistical summaries are deposited. Original ionograms, manual traces, individual E/Es/F-region parameters, per-observation SF labels, event catalogues and classifier assets are not redistributed.
The package supports direct inspection and replotting; observation-level model refitting requires separately authorized source records.
