The hole in the ozone layer over Antarctica in 2022 had an average area slightly smaller than the extent reached in 2021, and well below the average seen in 2006 when the hole size peaked.
An annual analysis of air samples collected at remote sites around the globe that is tracking a continued decline in the atmospheric concentration of ozone-depleting substances shows the threat to the ozone layer receding below a significant milestone in 2022, NOAA scientists have announced.
NOAA's Global Monitoring Laboratory (GML) held the grand opening ceremony for the Barrow Atmospheric Baseline Observatory (BRW) building in Utqiaġvik, Alaska, on Friday, August 5th, 2022.
Carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked for 2022 at 421 parts per million in May, pushing the atmosphere further into territory not seen for millions of years.
New research published in Atmospheric Chemistry and Physics projects future emissions of hydrofluorocarbons (HFCs), a class of potent greenhouse gasses, based on recent trends and compliance with current policies.
Greenhouse gas pollution caused by human activities trapped 49% more heat in the atmosphere in 2021 than they did in 1990, according to NOAA scientists.
NOAA Global Monitoring Laboratory has recently obtained approval from the FAA to fly the High-altitude Operational Returning Unmanned System (HORUS) up to 90,000 ft above mean sea level in the national airspace in northeastern Colorado.
Springtime (March-May) in the arctic is the prime time for surface ozone depletion events. Since March, several depletion events have been captured by surface ozone measurements at NOAA Barrow Atmospheric Research Observatory near Utqiaġvik, Alaska.
For the first time, the U.S. Environmental Protection Agency is using NOAA atmospheric measurements to help support a national inventory of emissions from an important family of greenhouse gases.
For the second year in a row, NOAA scientists observed a record annual increase in atmospheric levels of methane, a powerful, heat-trapping greenhouse gas that’s the second biggest contributor to human-caused global warming after carbon dioxide.
