2026-09-03 Sanya VHF Radar and Fuko Ionosonde Observations of Double-Layer Sporadic E (Es) Structures doi:10.57760/sciencedb.36981 en This dataset contains ionospheric sporadic E (Es) double-layer structure data observed by the Fuko ionosonde and Sanya VHF radar in Hainan, China, used to validate the TEC enhancement–based method for multi-layer Es identification using COSMIC radio occultation data. The data are concentrated in June 2013 and June 2015, covering the low-latitude region (18°N–19.5°N, 109°E–109.5°E). It includes Es layer height, electron density profiles, echo intensity, and temporal variations, supporting research on ionospheric Es structure, tidal modulation, and wind shear mechanisms.
