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.
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.
