A NOAA study published in Nature Geosciences takes a new look at faint, old smoke and finds that it is just as important an influence on the climate as the thick plumes produced by active fires.
NOAA has launched a wide-ranging research effort to investigate the impact of reduced vehicle traffic, air travel, shipping, manufacturing and other activities on Earth’s atmosphere and oceans due to the response to COVID-19.
A sooty cloud generated by a 2017 firestorm provided an ideal opportunity for researchers to test a climate model that simulated the lifetime of that soot in the stratosphere.
Findings could help improve air quality in cities across the U.S. West.
A a new NOAA study shows that during the morning rush hour in Boulder, Colorado, the trail of chemical vapors emitted by personal care products that commuters use on their skin and hair are comparable in magnitude to the emissions of major components of vehicle exhaust.
Chemical products like household cleaners, pesticides, paints and perfumes that contain compounds refined from petroleum now rival motor vehicle emissions as the top source of urban air pollution, according to a surprising NOAA-led study
People living in the American Southwest have experienced a dramatic increase in windblown dust storms in the last two decades, likely driven by large-scale changes in sea surface temperature in the Pacific Ocean drying the region’s soil, according to new NOAA-led research.
