Interpreting the Data: Understanding PM2.5 and AQI
Understanding the data displayed on the PurpleAir map is crucial for making informed decisions. The primary pollutant measured by PurpleAir sensors is PM2.5, which refers to fine particulate matter with a diameter of 2.5 micrometers or less. These tiny particles are particularly dangerous because they can penetrate deep into the lungs and even enter the bloodstream, posing significant health risks.
To make PM2.5 values more comprehensible to the public, government agencies use an Air Quality Index (AQI). The US EPA PM2.5 Air Quality Index (AQI) is a number used by US government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. This index translates PM2.5 concentrations into a simple numerical scale, with corresponding color codes and health advisories. For example, a low AQI typically indicates good air quality, while a high AQI suggests unhealthy conditions.
When comparing PurpleAir data with official government sources, it's important to note conversion factors. For instance, with two-minute updates, be sure to use hourly averages and the ECCC conversion on the PurpleAir map if you wish to compare the two maps (PurpleAir and official Canadian AQHI+). The same method of calculating PM2.5 as in [19] (referring to a scientific study or methodology) is often adopted, ensuring consistency in how the raw sensor data is translated into an AQI value.
