NOAA scientists and several partners are taking a fresh look at persistent air pollution problems bedeviling the nation’s two largest Intermountain metro regions, Denver and Salt Lake City, from the ground, in the air, and from space, during new research projects launched this month.

NOAA scientists investigating the stratosphere have found that in addition to meteoric ‘space dust,’ the atmosphere more than seven miles above the surface is peppered with particles containing a variety of metals from satellites and spent rocket boosters vaporized by the intense heat of re-entry.
While the shade offered by clouds on a hot sunny day can be obvious, quantifying the actual climate impact in terms of solar energy remains a challenging task. This is because the volume, thickness, and lifetime of marine clouds can change rapidly, and the processes that govern how and where clouds form and how gases and aerosols in the air interact with cloud droplets are highly complex. In a marine environment, many of those gases and aerosols in the air come from the ocean itself.

New NOAA analysis of a ground-breaking global atmospheric airborne research mission shows that smoke from biomass burning substantially contributes to one of the most common and harmful constituents of urban air pollution: ozone. Another record-breaking fire season across the western United States and Canada fouled skies as far downwind as Boston and New York City with wildfire smoke, visibly demonstrating the impacts that fires can have on air quality thousands of miles away. Now, new NOAA research demonstrates that the effects of fire emissions on the atmosphere are even larger and far more widespread than previously believed, and substantially contribute to one of the most common and harmful constituents of urban air pollution: ozone.
