Methodology
The extractor maps OpenAQ monitoring locations to the nearest AQI Now city in the same country, aggregates PM2.5 and PM10 to daily city averages, and converts those concentrations to US EPA AQI. Country tool pages use only city summaries that satisfy the configured minimum daily coverage threshold.
