When COVID-19 pandemic began in the US, counties and cities across the nation imposed stay at home orders, closed schools or imposed travel restrictions. From March 2020 onward, many Americans hung up car keys and settled into their homes for work and school. Traffic patterns dramatically changed, and previously smog filled vistas became clearer.
Findings could help improve air quality in cities across the U.S. West.
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.
A a new NOAA study shows that during the morning rush hour in Boulder, Colorado, the trail of chemical vapors emitted by personal care products that commuters use on their skin and hair are comparable in magnitude to the emissions of major components of vehicle exhaust.
The first peer-reviewed study to quantify oil and gas emissions on Colorado's northern Front Range confirms that energy development is an important contributor to the region’s chronic ozone problem. The NOAA-CIRES research was published August 8 in the Journal of Geophysical Research: Atmospheres.
From our nation’s founding, the Fourth of July has been synonymous with fireworks. While many grew up learning that fireworks can be dangerous to the eyes and hands if not handled properly, fireworks also produce air pollutants, including particulate matter, that are linked to short-term or long-term health effects.
NOAA has authored a new study appearing in the journal Atmospheric Environment that quantifies the surge in fine particulate matter – particles that are two and one half microns in diameter (PM2.5) – on July 4, using observations from the 315 U.S. air quality monitoring sites that operated from 1999 to 2013. The new study is the first nationwide quantitative analysis of the effects.
We sat down with Richard Artz, environmental scientist at NOAA’s Air Resources Laboratory, to learn more about the new global assessment of air pollutants that fall to the earth in precipitation and in dry form. The assessment is available online in the journal Atmospheric Environment.
Scientists this summer are taking one of the most detailed looks ever at the natural and manmade emissions that affect air quality in the Southeast, and their movement and chemical transformations within the atmosphere. The mission should help scientists determine the origin of the fine particles and how they contribute to the haziness in the region and affect regional air quality and temperature trends.
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.
