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.

Highlights of GML’s contributions to the 2020 BAMS State of the Climate Report

Scientists from Global Monitoring Laboratory contributed to the Bulletin of American Meteorological Society State of the Climate 2020 report report as editors and authors.

One step further towards day-ahead solar variability prediction

New research by GML characterized the relationship of solar irradiance variability with cloud properties and quantified that relationship using machine learning models.

GML CIRES employees received special recognition during the 2021 Rendezvous

Several CIRES employees in the Global Monitoring Laboratory received special recognition during the 2021 CIRES Rendezvous.

A new way to measure how Arctic plant communities respond to climate change

Modeling using atmospheric measurements of carbonyl sulfide (COS) was used for quantifying photosynthetic CO2 uptake in the Arctic and Boreal ecosystems.

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.

GML homogenizes a Cohesive Record for NOAA Ozone Data

The Global Monitoring Laboratory finished homogenizing multiple NOAA satellite and in-situ ozone records up until 2020, which will be used for trend analysis to understand the current status of ozone depletion in the stratosphere.

NOAA Federated Aerosol Network to add two new stations by the end of 2021

The NOAA Federated Aerosol Network (NFAN) is in the process of adding two new stations - one operated by the University of Miami at Ragged Point, Barbados, and one operated by the Air Force Institute of Technology at the Wright Patterson Air Force Base, Ohio.
