Major hurricanes, intense wildfires, increasing concentrations of greenhouse gasses, deep sea discoveries, and more made 2022 an eventful year for NOAA Research. As we enter the final days of the year, we’re taking a look back at some of our biggest accomplishments from the last 12 months.
A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin.
As research into engineering techniques that might one day be employed to artificially cool the planet advances, some scientists are calling for adoption of an oversight framework to guide what to study... and when to stop.
POPS is a low-cost, high-sensitivity alternative to traditional aerosol measurement technologies.
Findings of a new study of aerosols in the remote atmosphere finds that the northern stratosphere is significantlly more polluted than the south. Analysis of the aerosols suggests aviation is to blame.
The dynamics that lift smoke from large wildfires into the upper atmosphere could potentially be employed one day to help temporarily cool the planet, based on the findings of a modeling study led by NOAA scientists.
Massive high-altitude clouds of smoke warmed the Southern Hemisphere's stratospshere by about 1 degree Celsius for six months, and likely contributed to the large and persistent ozone hole that formed over Antarctica during the austral spring.
New research indicates that man-made clouds formed along shipping routes dissipate too quickly to provide insight into the cooling effect of naturally occuring marine clouds.
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.
NOAA's HRRR-Smoke model may still be designated as experimental, but when wildfires are burning, many count on it for smoke forecasts.
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.
