Analysis of fade dynamics and cloud absorption using beacon data and atmospheric profiles
Bibliographic record
Abstract
Fade duration, fade slope and cloud absorption are analyzed using results from measurements at CRC of the 20-GHz beacon of the Anik F2 satellite and from a 12-frequency profiling radiometer. The impact of low-pass filtering on fade duration and slope statistics derived from Anik F2 beacon data is discussed. The performance of four models predicting fade duration statistics, including one developed at CRC, is evaluated and discussed. Fade slope distributions show dependence on fade level and general symmetry between positive and negative slopes. Slope statistics are compared to predictions generated by the ITU-R model. The impact of absorption due to cloud liquid on the excess beacon attenuation is compared with predictions based on the ITU-R model, using the retrieved liquid water path and scaled cloud attenuation at 30 GHz extracted from the profiling radiometer brightness temperature data.

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.
