Variações na densidade eletrônica no pico da camada F ionosférica em São José dos Campos durante o ciclo solar 23
Bibliographic record
Abstract
In this investigation we used data obtained in Sao Jose dos Campos (23.2 ° S, 45.9 ° W) station located in the southern crest of the equatorial anomaly ionosferica through digital Ionosonde CADI (Canada Advanced Digital Ionosonde), at different times of solar cycle 23. This paper analyzes the behavior in the region of the ionospheric F layer, low latitude in the Brazilian sector. Using the data of maximum frequency at the peak of the F layer (foF2) during periods of high solar activity, solar activity and average low solar activity, we can see how the ionosphere in the region of the F layer behaved during the solar cycle variations. Emission data solar extreme-ultraviolet, were obtained by the SOHO satellite equipped with the Solar Extreme-Ultraviolet Monitor (SEM). We compared the ray emissions in the EUV band - 26-34 nm with a maximum frequency of F layer peak observed in Sao Jose dos Campos, indicating a decrease in foF2 and-ray emission in the band 26-34 nm with EUV solar activity that is 26-24 nm EUV does not show seasonal variations observed in foF2.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
