GML highlights at AGU 2022 Fall Meeting

GML and CIRES researchers are presenting several talks and posters at the 2022 Fall Meeting of the American Geophysical Union, and collaborating on many more.

Carbon dioxide now more than 50% higher than pre-industrial levels

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.

Greenhouse gas pollution trapped 49% more heat in 2021 than in 1990, NOAA finds

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.

HORUS is approved to fly in the national airspace in northeastern Colorado

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.

Increase in atmospheric methane set another record during 2021

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.

Modeling greenhouse gas emissions from atmospheric observations with Lei Hu

In celebration of Women’s History Month, this article continues a series of interviews with NOAA Research employees and scientists.

NOAA Global Monitoring Laboratory Development of a UAS “Virtual Tower” for Gas and Ozone Measurements

Scientists from NOAA’s Global Monitoring Laboratory (GML) have undertaken novel development of an uncrewed aircraft system (UAS) “hexacopter” that will enable the lab to not only recommence a long-standing mission that was recently forced to halt, but paves the way toward enhanced operations in the future.

GML highlights at AGU 2021 Fall Meeting

GML and CIRES researchers talks and posters at the 2021 Fall Meeting of the American Geophysical Union.

Southern Ocean confirmed as strong carbon dioxide sink

A new study published this week in the journal Science confirms the role of the Southern Ocean as a significant carbon sink.

GML's StratoCore will open a new era to study the stratosphere

GML and CIRES scientists are currently redesigning NOAA's balloon-borne AirCore sampler and increasing the number of gases measured from these samples.

Atmospheric carbon dioxide rebounds as global pollution rates approach pre-Covid levels

Global carbon emissions are projected to bounce back to 36.4 billion metric tons this year after an unprecedented drop caused by the response to the coronavirus pandemic.

NOAA data shed new light to improve NASA satellite products for carbon dioxide

New research shows that systematic errors in the OCO-2 total column CO₂ products can be large enough to confound reliable surface flux estimation.

Urban areas across the U.S. are undercounting methane emissions, a new study shows

An eight-year study of Boston’s natural gas system has revealed that emissions of methane, a powerful greenhouse gas, are significantly higher than previously estimated.

GML is granted funding to investigate COVID impacts on the U.S. non-CO2 greenhouse gas emissions

A new research initiative “Quantifying the impacts of COVID-19 on U.S. national and regional non-CO2 greenhouse gas emissions from atmospheric observations” is granted funding from Climate Program Office’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) program and Climate Observations and Monitoring (COM) program.

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.
