Fragrant consumer products a key source of ozone-forming pollution in New York City

Fragrant consumer products a key source of ozone-forming pollution in New York City

New research from NOAA finds that fragrant personal care products - the stuff that makes you smell good - are now responsible for a significant amount of the ozone pollution known as smog that plagues major urban areas.

Earth has two different stratospheres, and aviation may be to blame

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.

Study of wildfire plumes provide insights into methods that might cool the planet

Study of wildfire plumes provide insights into methods that might cool the planet

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.

Giant Australian bushfire injected 1 million tons of smoke in the atmosphere

Giant Australian bushfire injected 1 million tons of smoke in the atmosphere

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.

Emissions of a banned ozone-depleting gas are back on the decline

Emissions of a banned ozone-depleting gas are back on the decline

New analyses of global air measurements show that five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, they dropped sharply between 2018 and 2019.

Cooling effect of clouds generated by shipping overestimated, study says

Cooling effect of clouds generated by shipping overestimated, study says

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.

When smoke is in the air, all eyes turn to this NOAA weather model

When smoke is in the air, all eyes turn to this NOAA weather model

NOAA's HRRR-Smoke model may still be designated as experimental, but when wildfires are burning, many count on it for smoke forecasts.

New NOAA research model improves dust, air quality forecasts

New NOAA research model improves dust, air quality forecasts

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 new look at old smoke finds it has an important role in regulating the climate

A new look at old smoke finds it has an important role in regulating the climate

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.
