A new study looks into how air movement in the atmospheric boundary layer affects ozone removal by deciduous forests, which are a significant ozone sink.
Ozone loss, perhaps as a consequence of a warming climate, may have been responsible for a catastrophic loss of biodiversity.
A new case study investigates causes and effects of California’s 2017 wildfire season.
Past studies underestimated a major pollution source, particularly in rural areas.
Both the El Niño Southern Oscillation and natural variations in tropical Pacific weather conditions impact surface air quality in the Eastern United States.
Enhancements to the National Oceanic and Atmospheric Administration's decision support system give forecasters new capabilities for tracking smoke from fires using satellite data.
Researchers collected carbon from 3 years' worth of air samples and traced it back to its source.
A study suggests that known combustion and photochemical sources of nitrous acid, a precursor to ground-level ozone, are enough to explain levels seen in the atmosphere.
The presence of nitryl chloride in polluted urban air can enhance the production of ozone by up to 41%, according to a new modeling study constrained by ground-based measurements.
Reducing emissions of short-lived gaseous sulfur pollutants from power plants had an immediate, local benefit, but controlling longer-lasting harmful particulate matter will require regional action.
