Since the 1970s, the number of large-scale wildfires in the US, which spread across 10,000 acres (~4000+ hectares) or more, has increased fivefold. This is worrying because exposure to particles and gases associated with wildfire smoke often leads people to be hospitalized with breathing and heart-related problems.

To measure the impact of wildfires on air quality, Larsen and her colleagues analyzed different sources of relevant data collected between 2006 and 2013. The data included the US National Oceanic and Atmospheric Administration (NOAA) Hazard Mapping System (HMS) that gathers daily satellite information about the presence and spread of smoke plumes.

Also, the researchers referred to the US Environmental Protection Agency's Air Quality System which monitors air pollution levels at different sites across the US, and levels of ozone and fine particulate matter on a given day. Fine particles and ozone have been linked to a range of health problems.

Larsen and her colleagues found that ozone concentrations were on average 11.1 percent higher on days when plumes were seen than on clear days....
