Evolution of the stratospheric aerosol enhancement following the eruptions of Okmok and Kasatochi: Odin‐OSIRIS measurements
Bibliographic record
Abstract
Limb‐scattered sunlight measurements made by the OSIRIS instrument on the Odin spacecraft during the months following the eruptions of Mount Okmok and Kasatochi volcanos in 2008 are used to retrieve vertical profiles of the stratospheric aerosol extinction. These measurements reveal the evolution of the formation, transport, and decay of the stratospheric aerosol cloud that forms as a result of the volcanic eruptions. The maximum vertical optical depth of the stratospheric aerosol, measured by OSIRIS at 750 nm, occurs at midlatitude to high latitude 4 to 6 weeks after the Kasatochi eruption and is approximately a factor of 2 above the background level. Significant meridional transport in the lower stratosphere is evident in the observations, with measurable enhancement extending up to 21 km altitude and reaching tropical latitudes. Seven months following the eruption of Kasatochi, the stratospheric aerosol optical depth is very near the background level measured before the eruptions.

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.
