Warm air helped make 2017 ozone hole smallest since 1988

Warm air helped make 2017 ozone hole smallest since 1988

November 2, 2017
Measurements from satellites this year showed the hole in Earth’s ozone layer that forms over Antarctica each September was the smallest observed since 1988, scientists from NASA and NOAA announced today.
South Pole sees first sunrise in 6 months with arrival of spring

South Pole sees first sunrise in 6 months with arrival of spring

September 27, 2017
The fall equinox signals the coming of winter for the Northern Hemisphere, but heralds the arrival of spring — and the first sunrise since March — for researchers at NOAA’s South Pole Atmospheric Baseline Observatory.
Ozone treaty taking a bite out of US greenhouse gas emissions

Ozone treaty taking a bite out of US greenhouse gas emissions

August 14, 2017
The Montreal Protocol, the international treaty adopted to restore Earth’s protective ozone layer, has significantly reduced emissions of ozone-depleting chemicals from the United States. In a twist, a new study by NOAA and CIRES scientists shows the 30-year old treaty has had a major side benefit - reducing climate-altering greenhouse gas emissions from the U.S.
 After 2000-era plateau, global methane levels hitting new highs

After 2000-era plateau, global methane levels hitting new highs

July 12, 2017
Following a plateau in the early 2000s, global concentrations of the powerful greenhouse gas methane have hit new highs in recent years. Chemical fingerprint tests seem to rule out a major role for fossil fuels. With more than half a dozen possible natural and human sources, how will scientists figure out where it's coming from?
NOAA’s Greenhouse Gas Index up 40 percent since 1990

NOAA’s Greenhouse Gas Index up 40 percent since 1990

July 11, 2017
NOAA’s Annual Greenhouse Gas Index, which tracks the warming influence of long-lived greenhouse gases, has increased by 40 percent from 1990 to 2016 — with most of that attributable to rising carbon dioxide levels, according to NOAA climate scientists.
Possible new threat to Earth’s ozone layer

Possible new threat to Earth’s ozone layer

June 27, 2017
The Montreal Protocol has been hailed for controlling chlorine-based chemicals that created a vast hole in the ozone layer over Antarctica. But new research by British and American scientists suggest a chemical not controlled by the international treaty poses a potential risk to the Earth’s protective ozone layer.
As Alaska's North Slope warms, greenhouse gases have nowhere to go but up

As Alaska's North Slope warms, greenhouse gases have nowhere to go but up

June 12, 2017
The amount of carbon dioxide (CO2) being released from tundra in the northern region of Alaska during early winter has increased 70 percent since 1975, according to a new regional climate paper by scientists participating in a research project funded by NOAA and NASA.

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.
