NOAA’s new uncrewed glider poised to help vastly increase high-altitude research

Scientists from NOAA’s Global Monitoring Laboratory, are fine-tuning a low-tech, cost-effective system for lifting a small payload of specialized measuring instruments to the edge of space, and then guiding it back to the launch location.

An Early End to the 2021 Snow-Free Season in the Arctic

On September 19, 2021, the daily mean surface albedo at GML Barrow Atmospheric Baseline Observatory reached an albedo value greater than 0.6, indicating the end of the snow-free season in Utqiaġvik, Alaska.

The 2021 Ozone Hole – So it begins…

The 2021 Antarctic ozone hole is taking shape as we move into the ozone depletion season.

UCI researchers analyzed Antarctic air samples to learn of a 70-percent increase in atmospheric hydrogen over the past 150 years

NOAA Scientists contributed to a study by UCI researchers of air trapped in compacted layers of Antarctic ice and snow to come up with some answers and a few new questions about the amount of molecular hydrogen in our planet’s atmosphere.

First Annual Report Highlights Links Between Air Quality and Climate Change

Two CIRES scientists working in NOAA laboratories contributed to the WMO’s first-ever Air Quality and Climate Bulletin, released on September 3.

Keeping up the standard: Calibrating for accurate ozone monitoring

GML scientist Glen McConville and Lapenta intern Leah Barkai started the calibration of Dobson World standard instrument D083 at the GML Mauna Loa Observatory on July 12, 2021, and will continue the calibration until the end of August.

NOAA-NASA collaboration to study the impact of convective storms and the North American Summer Monsoon on stratospheric chemistry

Global Monitoring Laboratory and NASA team up in the DCOTSS (Dynamics and Chemistry of the Summer Stratosphere) project to study the convective impact of the North American Monsoon Anticyclone on stratospheric composition and ozone depletion.

Deforestation, warming flip part of Amazon forest from carbon sink to source

New results from a nine-year research project in the eastern Amazon rainforest finds that significant deforestation in eastern and southeastern Brazil has been associated with a long-term decrease in rainfall and increase in temperature during the dry season, turning what was once a forest that absorbed carbon dioxide into a source of planet-warming carbon dioxide emissions.

GML redesigning its 41-year-old, balloon-borne frost point hygrometer

The Global Monitoring Laboratory is currently redesigning the 41-year-old, balloon-borne frost point hygrometer that measures vertical profiles of water vapor from the surface to about 28 km above sea level in the middle stratosphere.
