Scientists from NOAA and The Aerospace Corp. modeled the climate response of the stratosphere to increased future emissions of black carbon from rockets burning kerosene fuel.
A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin.
A sooty cloud generated by a 2017 firestorm provided an ideal opportunity for researchers to test a climate model that simulated the lifetime of that soot in the stratosphere.
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.
A new study directly measures the heat-trapping effect of wildfires during an actual wildfire that burned near Boulder, Colo., in 2010.
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.
