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.
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.
World View Enterprises has offered to carry a miniaturized NOAA instrument on its high-altitude balloon to capture measurements of atmospheric particles on a series of flights in 2021 that will last weeks and cover thousands of miles at altitudes above 55,000 feet.
Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new NOAA study shows.
The hot and dry Santa Ana winds are associated with many of Southern California’s destructive wildfires, and even take the blame for tense, ugly moods. Now, NOAA researchers have found that on occasion the winds have an accomplice in contributing to California’s wildfires: atmospheric events known as stratospheric intrusions, which bring extremely dry air from the upper atmosphere down to the surface.
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.
