Measurements not from today will be faded

This view summarize the measurements on the static and mobile sensors currently displayed on the map.

Air Pollution Indication

The APIN shown* is the Air pollution Indication calculated from the concentrations of all the polutants. APIN goes from 1 to 5, where 1 represents better air quality and 5 represents worse air quality.

Each APIN value is asociated with one color:

  • 1 = green
  • 2 = green
  • 3 = orange
  • 4 = dark orange
  • 5 = red

APIN is based on the common Air Quality Index (CAQI) but we use 1 minute average and measurements that are not equivalent to reference instrumentation.

*The index APIN shown might not be current, check the measured date at the bottom of the screen.
