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.
Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited
ozone depletion in September and October, resulting in the smallest ozone hole observed since
1982, NASA and NOAA scientists reported today.
Record cold and record warm temperatures across the planet can cause major and widespread impacts to life and property. But how frequent are these extreme temperature events? How do the frequencies of record warm events and record cold events compare, and have their relative frequencies changed over time?
Our planet has been baking under the sun this summer as temperatures reached the hottest ever recorded and heat waves spread across the globe. While the climate continues to warm, scientists expect the frequency and intensity of heat waves to increase. However, a commonly overlooked aspect is the spatial size of heat waves, despite its important implications.
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.
