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.
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.
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.
NBC News aired a news story about the affect that the warming arctic has on the people of Barrow, Alaska. Included in the video is an interview with the Barrow NOAA observatory station chief Marty Martinsen. See the video here.
Since 2002, the Southern Ocean has been removing more of the greenhouse gas carbon dioxide (CO2) from the atmosphere, according to two new studies. These studies make use of millions of ship-based observations and a variety of data analysis techniques to conclude that the Southern Ocean has increasingly taken up more CO2 during the last 13 years.
Spring came early this year, breaking several records at the top of the world in Barrow, Alaska, according to a new report that combines observations from NOAA, the North Slope Borough and a scientist who has tracked an Arctic bird for the last four decades.
John A. Ogren, Patrick J. Sheridan and James W. Wendell of the Aerosol group in the ESRL Global Monitoring Division won the 2015 NOAA Technology Transfer Award, which recognizes achievements that are developed further as commercial applications, or that advance the transfer of NOAA science and technology to U.S. businesses, academia, other government and non-government entities.
About 170,000 pounds (76,000 kg) of the greenhouse gas methane leak per hour from the Barnett Shale region of Texas, including the urban areas of Dallas and Fort Worth, according to a new study led by NOAA/ESRL and Cooperative Institute for Research in Environmental Sciences (CIRES) researchers.
If you’re like me, when you hear the word “flask,” you’re likely to picture a grizzled, trail-weary cowboy gulping down a mouthful of whiskey from a tarnished, dented tin. But say “flask” to atmospheric chemist Steve Montzka, and he sees something more like a fire extinguisher or a stainless steel, two-liter soda bottle.
An international agreement in 2007 to deal with the last remaining ozone-depleting chemicals used in large quantities is working, according to a new analysis published today. Atmospheric emissions of those chemicals, called hydrochlorofluorocarbons (HCFCs) and used in refrigeration and air conditioning, are no longer increasing, after having increased consistently over the past few decades, according to NOAA measurements published in the Journal of Physical Chemistry
For the first time since we began tracking carbon dioxide in the global atmosphere, the monthly global average concentration of this greenhouse gas surpassed 400 parts per million in March 2015, according to NOAA’s latest results.
The American Chemical Society designated the Keeling Curve – a long-term record of rising carbon dioxide in the planet’s atmosphere -- as a National Historic Chemical Landmark in a ceremony April 30 at NOAA’s Mauna Loa Observatory in Hawaii.
A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, an area where the states of Arizona, New Mexico, Colorado and Utah meet at one point, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground, and with mobile laboratories.
