AI can help organize, compare, or model these data, but a model output remains an estimate with a defined place, time, pollutant, and uncertainty.
The EPA air-sensor guide recommends planning a study around a question, collecting measurements, and evaluating sensor performance. Lower-cost sensors can add observations, but they need careful interpretation and are not interchangeable with regulatory monitors. Mobile monitoring can reveal fine spatial variation while remaining temporally sparse at any one location. NASA’s TEMPO measures ozone, aerosols, and clouds from geostationary orbit and is designed for hourly air-pollution observations over North America. Satellites, ground monitors, and mobile instruments observe different scales; combining them does not directly measure each person’s exposure.
Compare a lower-cost sensor with a reference monitor during a planned collocation study.
Use mobile instruments to sample many street segments while recording when each observation was collected.
Compare satellite measurements with ground observations while accounting for their different spatial scales.
Communicate an AQI value with its pollutant, location, and forecast date.
Air-monitoring models may help compare observations and summarize patterns. Any future system should report its measurement sources, spatial and temporal coverage, validation results, and uncertainty, and should keep AQI communication distinct from a direct personal-exposure measurement.
