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.
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.
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 new NOAA and University of Michigan study using an instrumented airplane has found unexpectedly large emissions over five major cities along the East Coast - twice the total amount of methane and almost 10 times the amount estimated from natural gas.
New research finds the temperature of a wildfire is a better predictor of what’s in the smoke than the type of fuel being burned - a surprising result that will advance a wildfire smoke-modeling tool currently under development.
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.
A deep sea fishing rod is probably not the first tool that comes to mind when thinking about how to study air pollution in a remote inland desert, but it’s the heart of a new NOAA system that has given scientists a minute-by-minute look at how quickly the sun can convert oil and gas facility emissions to harmful ground-level ozone.
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.
