The giant methane cloud spotted by satellite over the U.S. Southwest that made national headlines in 2014 wasn’t a persistent, undiscovered “hotspot” as first thought, but the result of a nightly atmospheric condition and topography that trapped industrial and natural emissions of the potent greenhouse gas near the ground in the basin overnight, according to new research published in the journal Elementa by CIRES and NOAA.
A miniaturized aerosol spectrometer developed by scientists in NOAA’s Chemical Sciences Labotatory will be one of several insttuments making sure air in the living spaces of the International Space Station stays safe.
The study evaluated all of the aviation industry’s contributing factors to climate change, including emissions of carbon dioxide and nitrogen oxide, and the effect of contrails and contrail cirrus – short-lived clouds created in jet engine exhaust plumes at aircraft cruise altitudes that reflect sunlight during the day and trap heat trying to escape at night.
NOAA's HRRR-Smoke model may still be designated as experimental, but when wildfires are burning, many count on it for smoke forecasts.
Running on the newest version of NOAA’s Global Forecast System, or GFS, the FV3-Chem model forecasts the distribution of some primary air pollutants: smoke, soot, organic carbon, sulfate, and large and small particles of dust and sea salt - collectively known as aerosols. Because these aerosols affect the weather, the model also provides weather forecasts.
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’s powerful air quality model used to track pollution from wildfires, volcanoes and industrial accidents is now being used to help warn communities across Africa and Asia of what have been called the worst locust swarms in a quarter century.
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.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
