Consumer, industrial products now a major urban air pollution source

New study finds big impact from paints, pesticides, perfumes as vehicle emissions drop

Chemical products like household cleaners, pesticides, paints and perfumes that contain compounds refined from petroleum now rival motor vehicle emissions as the top source of urban air pollution, according to a surprising NOAA-led study

Methane leaks from three large U.S. natural gas fields in line with federal estimates

Methane leaks from three large U.S. natural gas fields in line with federal estimates

Cooperative Institute for Research in Environmental Sciences, NOAA researchers, colleagues measure lower emissions of the greenhouse gas than some other sites

Tens of thousands of pounds of methane leak per hour from equipment in three major natural gas basins that span Texas, Louisiana, Arkansas and Pennsylvania, according to airborne measurements published today by a NOAA-led team of scientists. But the overall leak rate from those basins is only about one percent of gas production there—lower than leak rates measured in other gas fields, and in line with federal estimates.

Nationwide study measures short-term spike in particulate matter due to Independence Day fireworks

Nationwide study measures short-term spike in particulate matter due to Independence Day fireworks

Particulate matter linked to short and long-term health effects

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.

New NOAA-led study measures soot from North Dakota  flaring in oil and gas fields

New NOAA-led study measures soot from North Dakota flaring in oil and gas fields

Flaring produces an estimated 4 tons of black carbon per day, not considered significant for climate

In the lonely reaches of northwestern North Dakota and across the border into Saskatchewan, the vast Bakken oil field hosts extensive activities to extract both crude oil and natural gas. Business is booming—production increased by 30 percent between May 2013 and May 2014. More than a quarter of the total gas produced from the Bakken operations can’t be processed fast enough, though, and the common industry practice is to flare it—burn it off as it is vented to the atmosphere. Jutting 30 feet upward like enormous lit matchsticks, the flares pose a new question for atmospheric scientists: What do the flares put into the air? A new NOAA-led study has produced the first direct measurements of how much black carbon—a major component of airborne particles that are commonly referred to as soot —is emitted by the Bakken flaring operations.

New research will help forecast bad ozone days over the western U.S.

New research will help forecast bad ozone days over the western U.S.

Forecasting can aid public education to minimize health effects of ozone

New research published in Nature Communications led by Meiyun Lin of NOAA’s Geophysical Fluid Dynamics Laboratory and NOAA’s cooperative institute at Princeton University, reveals a strong connection between high ozone days in the western U.S. during late spring and La Niña, an ocean-atmosphere phenomena that affects global weather patterns.
