Source scope
NWS observations
Quality-controlled station observations can be delayed by upstream processing. Statewide statistics summarize the balanced configured network and are not population-weighted.
NWS point forecast and alerts
A selected tract resolves an exact forecast grid point, nearest observation station, and active alerts for the tract point.
AirNow
Data provided by AirNow.gov. Current AQI and forecasts represent the returned reporting area. They are not an in-tract monitor reading or regulatory air-quality determination. No endorsement is implied.
California UCRI v2.0
Frozen tract screening context is displayed beside current conditions. Weather and AQI never alter the model score, rank, confidence, or priority band.
Statewide colors are nearest-station context from quality-controlled NWS observations and are not in-tract measurements. Selecting a tract resolves its exact NWS forecast grid, nearest observation station, active point alerts, and AirNow reporting area. California UCRI v2.0 is a separate frozen screening baseline and never changes with current weather. For emergency decisions, follow official local authorities and weather.gov.
