Abstract
Abstract The combined fields of view of the two Resolute Bay Incoherent Scatter Radars (RISR‐Canada and RISR‐North) significantly overlap the field of view of the Super Dual Auroral Radar Network (SuperDARN) radar located in Rankin Inlet. These radars measure ionospheric flow velocities in the polar cap region. Velocity data from the first multiple‐day combined operations of the two RISR radars and Rankin Inlet have been compared. Direct comparisons between line‐of‐sight measurements by both types of radars have been performed. These comparisons included data from 40 days of radar operations and used velocity data from 35 SuperDARN range gates (spanning 1,575 km). Overall, 5.2 × 10 5 comparison sets were analyzed. In particular during the daytime, signatures of groundscatter in the SuperDARN data often existed at most of the ranges considered in this comparison. This groundscatter could be partially removed from the comparison by only considering SuperDARN data points that had ionospheric velocity measurements in surrounding range cells. It was found that after removing groundscatter contamination at medium SuperDARN ranges (range gates 18–45), velocities measured by the two radar systems agreed when the high‐frequency results were adjusted to account for the refractive index effect. In regions dominated by groundscatter and E region scatter, lower SuperDARN velocities were measured and the overall comparison with the F region RISR velocities was poor.

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 it
