Candidate source investigations
This Air Quality Project now treats incinerators as one candidate source class among multiple plausible contributors. This makes the project more defensible, more useful and less vulnerable to confirmation-bias criticism.
Source classes
Road traffic
NO₂/PM near roads, fleet mix, congestion, street canyon and receptor exposure
Industry / large point sources
NAEI point-source context, permits, emissions returns, enforcement
Ports / shipping
NOx/SOx/PM context, harbour activity, wind direction and receptors
Landfill / waste transfer
odour, methane, bioaerosols and waste movements
Agriculture
ammonia, secondary particulate chemistry and rural background
Domestic burning
PM2.5, PAHs, seasonal evening patterns and local authority controls
Meteorology / long-range transport
inversions, wind sector, Saharan dust, regional episodes and CAMS context
Decision rule
A source class moves from candidate to stronger interpretation only after original-source review, monitor role, time alignment, meteorology, comparator context and reviewer challenge gates are satisfied.
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.
