The Annual Greenhouse Gas Index serves as a measure of global society's progress - or lack of progress - in reducing greenhouse gas emissions.
Accurate, high resolution weather forecasts equate to cost savings across many different industries, but it is not always clear exactly what those cost savings are.
NOAA atmospheric measurements are helping to support a national inventory of emissions from an important family of greenhouse gases.
A new NOAA modeling study suggests climate change is likely to disrupt Pacific atmospheric rivers, which are important sources of snow and rain for west coast states.
New research has identified two additional regions of Asia as contributing to rising emissions of the ozone-destroying chemical CFC-11 identified by NOAA scientists in 2018.
New research from a groundbreaking series of global airborne sampling flights reveals that desert dust is responsible for a significant fraction of icy cirrus clouds high in the atmosphere.
High background levels of ozone pollution make it hard for Las Vegas and other southwestern cities to meet US air quality standards in spring, two NOAA studies find.
But local pollution sources drive summer's high ozone days.
As research into engineering techniques that might one day be employed to artificially cool the planet advances, some scientists are calling for adoption of an oversight framework to guide what to study... and when to stop.
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.
A new study published this week in the journal Science estimates the Southern Ocean absorbs 550 million tonnes of carbon from the atmosphere per year, confirming its role as a significant carbon sink.
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.
