A climate science milestone on Colorado’s Continental Divide

A climate science milestone on Colorado’s Continental Divide

January 19, 2018
On January 16, 1968, an air sample collected at Niwot Ridge was measured for carbon dioxide at a lab in Boulder, Colorado--the first measurement for NOAA's Global Greenhouse Gas Reference Network. In the 50 years since, more than 274,000 air samples have been collected at over 60 sites around the globe.

Move of Bondville, IL Aerosol System to New Facility

December 15, 2017
Aerosol measurements have been made by the NOAA/ESRL Global Monitoring Division (GMD) at the Bondville Environmental and Atmospheric Research Site (BEARS) since June of 1994. In late October of 2017, the GMD aerosol monitoring system was moved from the aging, uninsulated sea container to a new temperature-controlled building about 80 meters away.

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

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.

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.
