HF scintillation in the high-latitude ionosphere
Bibliographic record
Abstract
In this presentation we will report on the first results of a multi-year study of high frequency (HF; 3-30 MHz) radio scintillation in the North American sector of the high-latitude ionosphere. We will focus on HF signals collected by the Radio Receiver Instrument (RRI) onboard the CASSIOPE spacecraft (also known as Swarm-E) during coordinated experiments between RRI the Super Dual Auroral Radar Network (SuperDARN) systems located at Saskatoon, Rankin Inlet, and Clyde River (all in Canada). The investigation's goals are to use the RRI data from the SuperDARN experiments to specify the nature of HF scintillation in the region, diagnose scintillation caused by ionospheric irregularities and distinguish it from scintillation resulting from HF radio propagation effects, identify geophysical phenomena responsible for HF scintillation, and ascertain the relationship (if any) between HF scintillation and backscatter measured by the SuperDARN systems.

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.
