  1. How does EPA guidance recommend evaluating a lower-cost air sensor?
    • Compare its measurements with a reference monitor under a planned study
    • Assume its readings are regulatory measurements without evaluation
    • Use it only to measure wind speed
    • Replace all measurements with a satellite image
  2. What tradeoff did the cited Google Street View mobile-monitoring study identify?
    • It improved temporal coverage but lost all spatial detail
    • It improved spatial detail but observations at any one location were temporally sparse
    • It measured every home continuously
    • It removed the need for ground measurements
  3. What does NASA’s TEMPO mission measure from geostationary orbit?
    • Ground-level personal exposure for every resident
    • Only indoor carbon dioxide
    • Ozone, aerosols, and clouds relevant to air quality
    • Traffic noise and vehicle speed
  4. What is the purpose of the Air Quality Index (AQI)?
    • To certify that a location has zero pollution
    • To measure a person’s exact inhaled dose
    • To rank air sensors by purchase price
    • To communicate air-pollution levels using health-concern categories
  5. Why can satellite observations and ground monitors complement one another?
    • They observe air quality at different spatial scales and measurement contexts
    • Each satellite observation equals an individual’s exposure
    • Ground monitors measure every point between stations
    • Combining them guarantees a correct forecast
  6. What does an AQI value not directly measure for an individual?
    • The pollutant category being communicated
    • The exact amount of pollution that person inhaled
    • The health-concern category associated with the reading
    • The measured or forecast air-quality level
  7. What information should accompany a public air-quality estimate?
    • Only the name of the algorithm
    • A guarantee that no pollution is present
    • The pollutant, measurement context, and relevant uncertainty
    • A claim that every sensor is equally accurate
  8. Why should a model’s air-quality estimate include uncertainty?
    • Every model always makes the same error
    • Uncertainty means the pollutant cannot be measured
    • A forecast without uncertainty is automatically accurate
    • Sensors, coverage, and model assumptions limit how precisely conditions are known
