Climate ESRL's Global Monitoring Division conducts sustained observations and research related to global distributions, trends, sources and sinks of atmospheric constituents that are capable of forcing change in the climate of the Earth. This research will advance climate projections and provide scientific policy-relevant, decision support information to enhance society's ability to plan and respond.

Ozone ESRL's Global Monitoring Division conducts research on the depletion of the global stratospheric ozone layer and Antarctic ozone hole through global surface-based monitoring of total-column ozone, ultraviolet radiation, and ozone-depleting gases, including those regulated by the Montreal Protocol. Continued surveillance is necessary in order to verify the expected recovery of the ozone layer.

Air Quality ESRL's Global Monitoring Division monitors levels of air quality elements such as tropospheric ozone, carbon monoxide and aerosol particles in non-source regions which may be affected by long range transport from distant sources of industrial pollution. This large-scale transport affects baseline air quality which must be monitored in order to determine the importance of regional sources that may impact the environment and public health.

Carbon dioxide levels rose at record pace for 2nd straight year

Carbon dioxide levels measured at NOAA’s Mauna Loa Baseline Atmospheric Observatory rose by 3 parts per million to 405.1 parts per million (ppm) in 2016, an increase that matched the record jump observed in 2015.

Unprecedented Arctic weather has scientists on edge

As station chief at NOAA’s Point Barrow, Alaska, observatory, Bryan Thomas works close to the edge of the Arctic Ocean. What he saw from his office in early February, looking north toward the horizon, was troubling.

Antarctic ozone hole about average in 2016

The hole in the Earth’s ozone layer that forms over Antarctica each September grew to about 8.9 million square miles in 2016 before starting to recover, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) who monitor the annual phenomenon.

4 ways the ozone hole is linked to climate, and 1 way it isn’t

To mark the peak of ozone hole season, we’re highlighting four ways that climate and the ozone hole are related—and one important way they aren’t.

Study finds fossil fuel methane emissions greater than previously estimated

Methane emissions from fossil fuel development around the world are up to 60 percent greater than estimated by previous studies, according to new research led by scientists from NOAA and CIRES.

Carbon dioxide levels race past troubling milestone

Carbon dioxide levels in the Earth’s atmosphere passed a troubling milestone for good this summer, locking in levels of the heat-trapping gas not seen for millions of years. Every year, the amount of carbon dioxide (CO2) rises during winter and then falls slightly during the Northern Hemisphere’s growing season, as plants take up this greenhouse gas during photosynthesis. But this year, for the first time since before the Ice Age, CO2 will not fall below 400 ppm.

Pacific Oxidants, Sulfur, Ice, Dehydration, and cONvection (POSIDON) Experiment

The NASA Pacific Oxidants, Sulfur, Ice, Dehydration, and cONvection (POSIDON) Experiment is a focused airborne science mission to study the ozone distribution, sulfur chemistry, very short-lived ozone depleting species (VSLS), cloud microphysics, and dehydration in the tropical upper troposphere and lower stratosphere over the western Pacific.

Research Groups

Global Greenhouse Gas Reference Network

The GGGRN makes measurements of the spatial and temporal distributions of greenhouse gases and provides essential constraints to our understanding of the global carbon cycle.

Halocarbons and other Trace Species

The HATS group quantifies the distributions and magnitudes of the sources and sinks for important ozone-depleting and greenhouse gases.

Aerosols

The goals of this program are to characterize means, variability, and trends of climate-forcing properties of different types of aerosols.

Global Radiation

Activities involve empirical and theoretical research of the Earth's surface radiation budget.

Ozone and Water Vapor

Research on the nature and causes of the depletion of the stratospheric ozone layer and the role of ozone and water vapor in forcing climate change.

Observatory Operations

NOAA/ESRL operates staffed atmospheric baseline observatories from which numerous in situ and remote atmospheric and solar measurements are conducted.
