GML’s surface radiation measurements improve NOAA’s operational weather forecast models

In a new study published in the AMS journal Monthly Weather Review, GML’s surface radiation measurements were key to helping researchers identify the source of a surface temperature bias in NOAA’s operational weather forecast models.

NOAA, NASA: 2025 ozone hole is 5th smallest since 1992

Scientists with NOAA and NASA have ranked this year’s ozone hole over the Antarctic as the fifth smallest since 1992 — the year that the Montreal Protocol, a landmark international agreement to phase out ozone-depleting chemicals began to take effect. During the height of this year’s ozone depletion season from September 7 through October 13, the average extent of the 2025 ozone hole was about 7.23 million square miles (18.71 million square kilometers). The ozone hole is already breaking up nearly three weeks earlier than average over the past decade. “As predicted, we’re seeing ozone holes trending smaller in area than they were in the early 2000s,” said Paul Newman, a senior scientist at the University of Maryland system and longtime leader of NASA’s ozone research team. “They’re forming later in the season and breaking up earlier.”

2024 Bronze Medal awarded to GML team for groundbreaking atmospheric observing platform

A team of scientists and engineers from NOAA’s Global Monitoring Laboratory has been awarded the Department of Commerce 2024 Bronze Medal for Scientific and Engineering Achievement for creating the High-altitude Operational Returning Uncrewed System (HORUS). The team is recognized “for developing a novel, low-cost, balloon-glider platform for deploying lightweight meteorological and atmospheric composition sampling and measurement systems to 90,000 feet and returning them to their original launch location.”

Bronze medal awarded to research team for SABRE

A team from CSL, GML, and CPO received a DOC Bronze Medal for scientific/engineering achievement "for establishing a new paradigm for NOAA-directed stratospheric science with the successful execution of the Stratospheric Aerosol processes, Budget and Radiative Effects (SABRE) 2023 airborne science mission."

New mobile NOAA Research fire weather observing facility undergoes testing in Colorado

A new, mobile fire weather observing system that can be quickly deployed to wildfire-prone regions to monitor how weather conditions contribute to fire ignition risk and behavior is undergoing testing and collecting data on a site near Boulder, Colorado. The mobile system, called “Collaborative Lower Atmospheric Mobile Profiling System” (CLAMPS), is one of several new NOAA fire weather observation systems developed during the past few years. It is a joint project between Air Resources Laboratory (ARL), Global Monitoring Laboratory (GML), Global Systems Laboratory (GSL), and Physical Sciences Laboratory (PSL), and is a key part of NOAA’s larger effort to advance our understanding of the interactions between wildfires and weather.

Photo feature: Last light at South Pole brings 6 months of darkness

In the Northern Hemisphere, March 20 signals the start of spring. It's the start of fall in the Southern Hemisphere, where researchers and staff at NOAA’s South Pole Observatory recently witnessed the fading light of the sun and the start of six months of darkness.

GML’s 20-year water vapor record at Lauder, New Zealand

The NOAA Global Monitoring Laboratory has reached a milestone: the longest continuous upper atmospheric water vapor record in the southern hemisphere.

Biden-Harris Administration, NOAA invest $15 million to help protect Western U.S. communities from wildfire

The Department of Commerce and NOAA announced today that approximately $15 million has been provided through the Bipartisan Infrastructure Law to construct and deploy a new suite of fire weather observing systems in high-risk locations in the Western United States to support wildfire prediction, detection and monitoring.

GML highlights at the 2025 AMS annual meeting

GML and CIRES researchers and summer interns are presenting several talks and posters, and collaborating on others, at the 2025 annual meeting of the American Meteorological Society. The meeting runs from January 12 – 16 in New Orleans.

Wildfires accompanied past periods of abrupt climate change

During the last glacial period, when large swaths of the North American continent were covered in ice, rapid, repeating shifts in temperature and tropical rainfall continually altered environments around the world. A new study led by a CIRES/GML researcher finds past wildfire activity tracked the abrupt changes in climate — burning increased when rainfall decreased.

A year of science and innovation: Reflections from 2024 on building a safer and more resilient nation

Changes in our weather, air quality, ocean, and Great Lakes continue to affect almost every aspect of society. Throughout 2024, NOAA Research has continued to study the Earth to better understand the challenges Americans are facing. Learn about how NOAA Research scientists are working to protect economic prosperity, national security, human and environmental health through our science and innovations.

GML’s Laura Riihimaki Appointed Project Manager of the Baseline Surface Radiation Network

Laura Riihimaki, a scientist in NOAA’s Global Monitoring Laboratory, has been appointed as Project Manager of the Baseline Surface Radiation Network (BSRN), leading international efforts to make long-term, high-quality surface radiation budget measurements.

GML highlights at AGU 2024 Fall Meeting

GML and CIRES researchers are presenting several talks and posters at the 2024 Fall Meeting of the American Geophysical Union and collaborating on many more.

NOAA’s GOES Satellites Can Provide Quicker Detection of Large Methane Emissions

Innovative use of NOAA’s geostationary satellites (GOES) has given scientists a new way to detect large methane emissions faster and more accurately. NOAA scientists say the experimental verification of GOES methane data will lead to faster, more complete data on the location—and amount—of methane emissions and successful mitigation efforts, when there are accidental leaks.

No sign of fossil fuel pollution peak as the world falls further behind climate targets

Emissions of carbon caused by fossil fuel pollution continued to grow slightly in 2023 to 36.8 billion metric tons of carbon dioxide, setting yet another new record despite increasingly urgent warnings from scientists about the need for steep and immediate decreases. NOAA provides about a quarter of all the atmospheric CO2 observations and about half of all the surface ocean CO2 observations used in the analysis.
