Dust and smoke are turning Colorado’s blue skies red. where is it coming from

Blowing dust and smoke from fires, dry land and construction have periodically turned Colorado’s blue skies red this spring, and air quality experts predict more crazy haze in the future as wind blows from the dry Southwest. spoils the particles.

Nasal-level concentrations of tiny, lung-dwelling particles reached 207 micrograms per cubic meter over a 24-hour average at 4:30 p.m. Monday in Colorado Springs. That’s 33% more than the federal health limit of 155 micrograms. Levels rose to 422 at a state watch near Colorado College before sunrise, then quickly dissipated — a challenge for state officials tasked with keeping public health warnings current.

A mix of multiple sources, state and federal meteorologists said, is because strong winds move the clouds. Wildfire smoke from New Mexico, where the fires have burned more than 250,000 acres, has risen in high-level air currents. Dust from the bone-dry Four Corners area and other landscapes reached Colorado’s Urban Front Range. And the exposed grit from common construction sites, where the topsoil has been removed, accelerates the air-churning brew.

Sometimes visibility drops to less than five miles, a measure state health officials say residents can use to determine whether the air is unhealthy to breathe. From Metro Denver South to Trinidad this week, residents couldn’t see the mountains from time to time.

Expect more of the same with above-average heat, red-flag fire risk, and no rain forecast during this week.

And more are expected in the future, if current climate trends continue, said Jeff Derry, director of the Center for Snow and Avalanche Studies, who has been monitoring the National Oceanic and Atmospheric Administration satellite imagery and dust on mountain snowpack since 2002. .

“Drought and summer mean we will probably see more fires. That is, more smoke. For dust, with stressed vegetation and less water on the landscape in the dust source areas of the Southwest, we should probably expect more dust,” Derry said.

On Tuesday, September 7, 2021, motorists drive towards a foggy city near exit 213 on I-25 south. A haze covered the metro area as Denver’s air quality dropped to moderately poor levels.

“All science is pointing in that direction. This means a decrease in air quality. And that means more dust in the mountains on the snowpack,” he said. “This ice is going to melt fast. Earlier melting of ice usually means less water later in the summer. ,

National Weather Service meteorologists monitoring satellite images have tracked several wind-driven plumes spreading across Colorado.

The significant smoke from New Mexico wildfires “is not necessarily what some people smell, but it looks hazy”, said NWS meteorologist Kari Bowen. “And then there’s some dust over northwest New Mexico. And localized dust can pick up. If people live near construction sites, and it’s a little windy, they can see dust like that,” Bowen said. “Landscapes can be very dry, which creates the potential for a certain wind speed to lift more of that dirt and carry it when it dries.”

State health officials issued an unhealthy air warning for vulnerable people (children, the elderly and the vulnerable) in the Colorado Springs area on Monday and Tuesday. Metro Denver’s air quality deteriorated to “moderate” in unhealthy conditions. The residents encountered vary by location and fluctuate.

“The best thing to do is to always be aware of the air quality at your location,” said Dan Welsh, an air quality meteorologist with the Colorado Department of Public Health and the Environment. Sunday as “notable in intensity for a short period”.

Colorado residents can check government-run websites (colorado.gov/air quality and airnow.gov) and “take any health precautions you may need,” Welsh said.

Medical experts warn of a potential “compound effect” as the particles mix with ground-level ozone pollution, for which Colorado has been deemed a “serious” violator of federal health standards. The wind also spreads pollen that plagues residents with allergies.

“You start to get a lot of chemical reactions,” said Dr. Mark Ereth, an emeritus professor at the Mayo Clinic who serves on the boards of air filtration companies and guides the American Society of Heating, Refrigerating and Air-Conditioning Engineers. helps.”

The sun is hidden by heavy smoke from the NCAR fire in Boulder, Saturday, March 26, 2022.

“We need to look at the concept of our lifetime performance,” Areth said.

“Particles cross into your bloodstream. They’re taken up by your organs. That’s where they introduce inflammation. Inflammation is a source of hardening of the arteries and cerebrovascular diseases,” he said. You have to modify your indoor and outdoor lifestyle based on the quality of life.….. There is no doubt that breathing clean air will extend your life.”
