Things are looking up a bit in Visalia-Tulare County, which moved down the list one spot from last year’s second-place ranking for ozone. It stayed in third place, though, for year-round air particle pollution. Tulare County, located in California’s San Joaquin Valley, is home to only about 460,000 people but more than 1 million cattle. Industrial dairies play a big part in local air pollution, which includes high levels of methane emissions.

The Fresno-Madera-Hanford metro area only has 1.3 million residents. They enjoyed the lowest number of ozone days since 2000, but stayed in the same spot on the list as last year. In addition to the number of cars on the road, geography is partly to blame. The bowl-shaped San Joaquin Valley traps vehicle emissions with no way for them to get out.

Arizona has less cloud cover than any other state. And Phoenix is the state’s second-sunniest city. More sunlight reaching the ground means more ozone. That could be why Phoenix moved up the list two spots from No. 7 last year. To clean things up, local leaders are working to curb the number of drivers on the road and to cap the use of wood-burning fire pits and fireworks.

The Sacramento Valley is shaped like a bowl. In summer, pollutants like exhaust from cars get trapped closer to the ground. The Sacramento-Roseville metro area, home to 2.6 million, earned a spot on the lists for highest ozone days, most unhealthy spikes in particle pollution, and annual particle pollution levels.

The San Diego-Chula Vista-Carlsbad metro area scored an F on this year’s ozone report, with more than 100 days of high readings. The toxic air is bad news for the metro area’s more than 300,000 kids and adults with some form of asthma.

Colorado is working to meet a June 2021 EPA compliance deadline for lowering ground ozone levels. Strict oil and gas regulations helped, as did having fewer of the Denver-Aurora metro area’s 3.6 million residents on the road during the COVID-19 pandemic. But rising temperatures and drier weather have also led to a jump in wildfires throughout the state.

Utah’s capital, along with most of the state’s population, is positioned in front of the Wasatch Mountains. In winter, temperature inversions -- a layer of high warm air aloft -- traps cooler air below. That means pollution created by the Salt Lake-Provo-Orem area’s 2.5 million residents has nowhere to go.

Think of the Bay Area as a big bowl. Winds make it easy for polluted air to move from one valley to another. Vehicles driven by the nearly 9 million residents of San Francisco, San Jose, and Oakland play a role in the area’s dirty air. During warm months, residents can get daily updates on air quality from the Bay Area Air Quality Management District’s Spare the Air campaign.

2021 marks the 51st year of America’s Clean Air Act, a law passed to improve air quality. But more than half a century later, many U.S. cities still have unhealthy levels of smog, according to the American Lung Association’s annual State of the Air rankings. Warming trends from climate change increase ozone and, along with frequent wildfires, worsen air quality.
