Database of in-plume emission factors from open demilitarization of military ordnance
Bibliographic record
Abstract
A searchable database of emission factors from open burning, open detonation, and static firing of military ordnance and rocket motors has been developed and made available. Sampling and analytical results since 2010 have been compiled from seven campaigns in the USA and Canada at four different sites. Various ordnance types were used for multiple test scenarios varying location, soil covered/uncovered, metal-cased and uncased, and net explosive weight. Target compounds include, variously, particulate matter, metals, energetics, volatile organic compounds, and others. Data were primarily derived from unmanned aerial sampling methods using ordnance charge sizes and procedures representative of operational demilitarization operations. The database includes 1,212 emission factors for 39 different types of munitions and an array of pollutants where open burns accounted for 514 scenarios, static firing for 83, and open detonation for 614. The database will be of use for risk evaluations, environmental reporting requirements, and demilitarization operations.
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.

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.
