Air-quality methodology, source caveats, and editorial standards

Thaddeus Veld oversees how AirHistory documents its methodology and editorial standards for EPA AQS data. The role sets how the quarterly AQS pull and reporting lag are explained, how under-monitored counties and regional-proxy monitors are flagged, and how corrections are handled. Methodology, guides, and explainers are AI-assisted in research and drafting, then reviewed against the primary EPA AQS and AirNow sources before publication.
