Polar patches: Auroral zone precipitation effects
Bibliographic record
Abstract
We look at patches observed by digital ionosondes in the northern polar cap. These observations show that patches have the following properties. (1) Patches are relatively large, typically ∼500 km in the sunward‐antisunward direction and ∼1000 km in the dawn‐dusk direction. (2) When the IMF Bz has abnormally large positive‐negative swings the patches show correlation with the IMF Bz swings. (3) For typical days the patches show no average correlation with IMF By and only weak correlation with negative IMF Bz. (4) Patches are slightly weaker in summer. The typical patch max‐to‐min Ne variation in winter is ∼2 × 10 11 el/m 3 and in summer it is ∼1.5 × 10 11 el/m 3 . (5) There is restructuring of patches, particularly the small‐scale structures, as the patches convect across the polar cap. (6) Patches are formed prior to entering the polar cap and their properties stay about the same thereafter. We explain the patch generation and most of these properties by low‐energy precipitation into the returning flow from the nightside to the dayside around the dawn convection cell.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
