Short summary
We studied unusual winter air pollution in Utah's Uinta Basin, where ozone levels exceed safety standards despite cold temperatures. Using an air quality model, we found hydrocarbon compounds from oil and gas operations transform into formaldehyde and other chemicals during winter photochemical events. Light alkanes were the biggest contributors to pollution formation. Understanding these mechanisms helps identify compounds to target for emission reductions in oil and gas regions.
