NOAA scientist Andrew Rollins was unsatisfied with the current, research-grade instrument for measuring nitrogen oxides. So he built a better one.
A team led by NOAA researchers used a combination of observations and computer models to generate the first broad assessment of bottom marine heat waves in the productive continental shelf waters surrounding North America.
A new NOAA analysis shows U.S. emissions estimates of the super-potent greenhouse gas sulfur hexafluoride and shows they have declined between 2007-2018.
Flying out of Eielson Air Force Base in Fairbanks, Alaska, a NASA WB-57 research jet carrying a payload of sampling instruments into the stratosphere will gather measurements of trace gases and aerosols in an undersampled region of the atmosphere.
Smoke from wildfire-generated thunderstorms has greater impacts on the stratosphre, lasts longer and acts differently than scientists previously thought, a new research paper in the journal Science concludes.
A scientist with NOAA's Pacific Marine Environmental Laboratory led development of a guide to help marine resource managers use environmental DNA to collect detailed information about the biodiversity of their study areas.
Scientists have long known that the sun drive photochemical reactions responsible for generating ozone and particulate pollution that is harmful to human health. But what happens when the sun goes down? A new study co-authored by a Chemical Sciences Laboratory resesearcher provides insight into what happens with air pollution in the dark of the night..
Montzka, senior scientist for the Global Monitoring Laboratory, is recognized for his distinguished contributions to the field of atmospheric sciences, particularly for measuring and interpreting trends in greenhouse gas and ozone-depleting substance concentrations worldwide. He is among 26 AAAS Fellows elected from NOAA since 1976.
The 2.4 million people who live along Utah’s Wasatch Front experience some of the most severe winter particulate matter air pollution in the nation. Now, analysis of measurements taken during NOAA research flights in 2017 indicates that emissions from a single source, a magnesium refinery, may be responsible for a significant fraction of the fine particles that form the dense winter brown clouds that hang over Salt Lake City.
An annual analysis of air samples collected at remote sites around the globe that is tracking a continued decline in the atmospheric concentration of ozone-depleting substances shows the threat to the ozone layer receding below a significant milestone in 2022, NOAA scientists have announced.
