Bounce‐averaged diffusion coefficients for field‐aligned chorus waves
Bibliographic record
Abstract
Whistler mode chorus emissions in the Earth's magnetosphere extend from the plasmapause to the boundary of trapping. Knowledge of the pitch angle and energy scattering rates is essential for accurate radiation belt modeling. Scattering rates, which are used as an input for radiation belt codes, should be evaluated dynamically and should account for the changes in plasma density, latitudinal and MLT distribution of waves, and wave spectral properties. Bounce‐averaged diffusion coefficients computed with the assumption of parallel wave propagation are compared to the results of the PADIE diffusion code, which takes into account the oblique propagation of waves and higher‐order resonances. The inaccuracies associated with the neglect of higher‐order resonances are compared to potential errors introduced by inaccuracies in determining plasma density and the latitudinal distribution of waves. Numerical sensitivity tests show that the errors associated with the neglect of the high‐order scattering are smaller than inaccuracies associated with the uncertainties in the parameters of the codes.

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.
