National emissions inventory context
NAEI resources help This Air Quality Project avoid single-source bias by identifying wider sector, large-point-source and gridded emissions context. This supports candidate-source investigation rather than direct source attribution.

Scientific evidence and software assurance are different
Scientific evidence
Measurements, station and regional coverage, descriptive calculations, source records and stated limitations are the evidence available for review.
Engineering assurance
Automated checks confirm that the pipeline followed its declared rules. They do not constitute peer review, accreditation, regulatory approval or institutional endorsement.
