Abstract

fetched live from OpenAlex

Abstract. Fast, charged particles intermittently rain down into Earth's dense atmosphere. The kinetic energy of these particles are converted into heat and light, and it ionizes the atmospheric gas, providing a source of both free and bound energy for the ionosphere; this is the aurora borealis and australis. The specific kinetic energy of the constituent particles in the aurora dictates the atmospheric response to the ongoing particle precipitation, with hard (high-energy) particles penetrating deeper than those that are considered soft (possessing a low kinetic energy). In this paper, we analyze a large database of precipitating particle observations from the United States' Defense Meteorological Satellite Program, and aggregate the altitude-dependent response of the ionosphere at high-latitudes, using fast ionization rate parameterizations due to two important papers by Fang et al. (10.1029/2010GL045406 and 10.1002/jgra.50484). We explore a characteristic altitude-dependent pattern in space (magnetic latitude and longitude), and time (geomagnetic activity), pertaining to the shape of the northern hemisphere, high-latitude ionosphere during local winter. We briefly discuss the implied ratio of E- to F-region Pedersen conductance, and this ratio's ramifications for the growth & decay (and thus proliferation) of plasma turbulence in the high-latitude ionosphere.

Full frame distilled prediction

Teacher imitation

Not 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.
