below show the dispersion of wildfire smoke, the total levels of fine particulate matter (PM2.5), ground level ozone (O3) and nitrogen dioxide (NO2) hourly emissions for the next 72 hours. These are the three pollutants used to calculate the Air Quality Health Index (AQHI).

During wildfires, smoke is the dominant emission shown on the maps.</p> <h2 class="h3"><a href="/firework/firework_anim_e.html?type=o3&utc=12">Ozone</a></h2> <p>The ozone map shows ground-level ozone, a major contributor to smog. The map shows how ozone can be transported long distances from its source.</p> <h2 class="h3"><a href="/firework/firework_anim_e.html?type=no2&utc=12">Nitrogen dioxide</a></h2> <p>The nitrogen dioxide map shows the amount of NO2 emissions in the air.
