SULFUR DIOXIDE FROM THE ATMOSPHERIC CHEMISTRY EXPERIMENT (ACE) SATELLITE
Bibliographic record
Abstract
The version 4.0 dataset from the Atmospheric Chemistry Experiment -Fourier Transform Spectrometer (ACE-FTS) on SCISAT, released in March of 2019, has sulfur dioxide (SO 2 ) volume mixing ratio (VMR) profiles as a routine data product.From this dataset, global SO 2 distributions between the altitudes of 10.5 km and 23.5 km are analyzed.The global distribution of all SO 2 VMR data by altitude is divided into 30 and 5 latitude zones.Seasonality of global SO 2 distribution is explored.Volcanic SO 2 plumes are isolated in the dataset and compared with aerosol extinction data from the ACE-FTS Imager.SO 2 is converted to sulfate aerosols on a timescale of about one month.Sulfate aerosols increase the Earth's albedo and cool the surface.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
