Commerce building now part of NOAA, NIST weather and greenhouse gas tracking network

NOAA and NIST have installed a Doppler lidar instrument to an existing weather station on top of the Department of Commerce’s Herbert Clark Hoover Building in Washington, D.C. to measure wind flow and turbulence in the lowest part of the atmosphere for a research project studying greenhouse gas emissions in the Capitol area.

Tracking fossil fuel emissions with carbon-14

Tracking fossil fuel emissions with carbon-14

Researchers from NOAA and the University of Colorado Boulder have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon that scientists have relied on for decades to date archaeological sites.

Warming influence of greenhouse gases continues to rise, NOAA finds

Warming influence of greenhouse gases continues to rise, NOAA finds

NOAA’s Annual Greenhouse Gas Index tracks the concentrations of greenhouse gases being added to the atmosphere principally from human-caused emissions. The AGGI then calculates the heat being added to Earth's atmosphere and oceans as a result.

Healing ozone layer stopped migration of Southern Hemisphere winds

Healing ozone layer stopped migration of Southern Hemisphere winds

A NOAA study published in the journal Nature demonstrates a profound effect of the Montreal Protocol: as levels of ozone-depleting chemicals controlled by the intenational treaty declined, a poleward shift of summertime circulation patterns in the Southern Hemisphere halted.

Carbon dioxide levels hit record peak in May

Carbon dioxide levels hit record peak in May

Carbon dioxide levels reached the highest seasonal peak recorded in 61 years of observations at NOAA's Mauna Loa observatory. This the seventh consecutive year of steep global increases in concentrations of this important greenhouse gas pollutant.

Ozone hole modest despite conditions ripe for depletion

Ozone hole modest despite conditions ripe for depletion

Weather conditions were ripe for a big ozone hole this year. But declining levels of ozone-depleting chemicals kept it to near-average size.

ABOUT US

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 theĀ NOAA, a bureau of theĀ 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.
