An eight-year study of Boston’s natural gas system has revealed that emissions of methane, a powerful greenhouse gas, are significantly higher than previously estimated.

Understanding how wildfires impact air pollution and the composition of Earth’s atmosphere is critical for communities near and far because smoke from wildfires can travel long distances and have adverse health impacts on citizens.
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.
