Washington D.C. air quality tracker: Smoke pollution improves in nation's capital

Air quality has vastly improved in Washington Friday after spending hours in wildfire smoke levels considered “hazardous” on Thursday.

WASHINGTON - Air quality has vastly improved in Washington Friday after spending hours in wildfire smoke levels considered "hazardous" on Thursday.

Air Quality Index (AQI) levels were under 100 across the Washington and Baltimore areas Friday morning, only ranking in the "moderate" category. 

The air quality in Washington had skyrocketed to "hazardous" levels for part of Thursday morning before falling back to "Very Unhealthy" levels as millions of people in the Northeast and mid-Atlantic were smothered in thick smoke blowing in from hundreds of wildfires burning in Canada.

Images from around the nation's capital showed an orange haze in the sky Thursday, much like what New York City experienced on Wednesday.

People visiting many of the monuments in Washington, as well as national park rangers, were seen wearing masks to protect themselves from the harmful effects of the wildfire smoke.

By Friday, just a light haze loomed over the nation's capital.

The Washington air quality levels reached "hazardous" levels on Thursday morning when the Air Quality Index (AQI) hit 313. Those levels dropped a bit to "Very Unhealthy" levels later in the morning.

The AQI ranges from 0 to 500 and has six color-coded categories to correspond to a different level of health concern, according to AirNow.gov. Lower numbers equate to better air quality, and higher numbers equate to poorer air quality.

WHAT IS THE AIR QUALITY INDEX?

What does the Air Quality Index (AQI) mean?

A regular assessment of air quality in the United States started in 1976, about six years after the Environmental Protection Agency was created.

According to AirNow.gov, the law requires any metropolitan area with a population of more than 350,000 to report air quality daily.

The Air Quality Indexs we know it today was released in 1999, according to AirNow.gov. It has gone through several updates over the years, but the goal has always been the same — to offer people an easy-to-understand daily report about the air they’re breathing and indicate what air quality is dangerous.
