Rising ozone pollution in Antarctica over the last 26 years

New research has found that surface ozone measured in Antarctica has been rising over the last 26 years (1992-2018).

New research suggests no significant reduction in total oil and natural gas emissions from 2008 to 2016 in Weld County, Colorado

New research suggests no evident reduction in total oil and natural gas emissions and their contribution to the regional air quality from 2008 to 2016 in Weld County, in Northeastern Colorado.

Remote monitoring towers provide data that advance the understanding of boreal forest fires

Boreal forest fires influence the global carbon cycle and climate system by consuming aboveground and underground biomass and directly releasing carbon dioxide, other trace gases, and aerosols into the atmosphere. A new study with GML co-authors quantified emission factors of carbon monoxide and methane using ground-based observations from the Carbon in Arctic Reservoirs Vulnerability Experiment (CRV) tower in Alaska.

New analysis shows microbial sources fueling rise of atmospheric methane

The sudden and sustained rise in atmospheric levels of the potent greenhouse gas methane since 2007 has posed one of the most significant and pressing questions in climate research. A research team led by CIRES and NOAA scientists has tested the leading theories for surging methane levels by analyzing the stable carbon isotope ratios (δ13C-CH4) from methane captured in a large set of global air samples.

2021 snow-free season started on June 14 at GML Barrow Observatory

On June 14, 2021, the daily mean surface albedo at Global Monitoring Laboratory (GML) Barrow Atmospheric Baseline Observatory dropped below 0.3, indicating the start of the snow-free season. The snowmelt day ranked 6th latest of the latest 24 years and 44th latest since 1926.

Carbon dioxide peaks near 420 parts per million at Mauna Loa observatory

Atmospheric carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked for 2021 in May at a monthly average of 419 parts per million (ppm), the highest level since accurate measurements began 63 years ago, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.

GML scientists successfully test high-altitude return glider with the AirCore science package

Global Monitoring Laboratory (GML) and Cooperative Institute for Research in Environmental Sciences (CIRES) scientists successfully tested a new method for high-altitude air sampling and instrument recovery from May 13-25, 2021.

NOAA, Boeing team up to test greenhouse gas-measuring technology

NOAA and Boeing are teaming up to evaluate the best placement for a NOAA greenhouse gas sampling system on a commercial jet by testing options on a new Boeing 737 as part of Boeing’s 2021 ecoDemonstrator flying test bed program.

Asian American, Native Hawaiian, and Pacific Islanders Heritage Month: A Conversation with Field Operations Chief Gataivai “Vai” Talamoa

In honor of Asian American, Native Hawaiian, and Pacific Islanders (AANHPI) Heritage Month, Global Monitoring Laboratory (GML) is highlighting the great work done by our Field Operations Liaison Gataivai Talamoa (known as “Vai”) at the American Samoa Observatory (SMO) and NOAA Pacific Islands Fisheries Science Center (PIFSC).

NOAA index tracks how greenhouse gas pollution amplified global warming in 2020

Extra heat trapped in the atmosphere by human-caused greenhouse gas pollution continued to exacerbate global warming in 2020

NOAA’s Global Monitoring Laboratory Testing High-Altitude Operational Returning Unmanned System at NASA’s Armstrong Flight Research Center and Edwards Air Force Base

Global Monitoring Laboratory (GML) and Cooperative Institute for Research in Environmental Sciences (CIRES) scientists are launching a new AirCore field campaign to test a new method for high-altitude air sampling and instrument recovery.

5 ways NOAA scientists are answering big questions about climate change

Scientists at NOAA have long worked to track, understand and predict how climate change is progressing and impacting ecosystems, communities and economies. This Earth Day, take a look at five ways scientists are studying this far-reaching global trend.

Can we see a change in the CO2 record because of COVID-19?

Despite pandemic shutdowns, carbon dioxide and methane surged in 2020

Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response.

Women’s History Month: A conversation with NOAA Corps Officer LTJG Marisa about her 13 months “on the ice”

In honor of Women’s History Month, Global Monitoring Laboratory (GML) is highlighting some of the great work done by our scientists. Today’s story expands on a previous one introducing a day in the life at the South Pole for NOAA Corps Officer Lieutenant Junior Grade Marisa Gedney, who served as a Station Officer at the Amundsen-Scott South Pole Station in Antarctica.
