GMD Team Members of the Quarter

The HATS flask analysis team of Debbie Mondeel, Carolina Siso, and David Nance have provided important analyses of the recent atmospheric growth increase of CFC-11, an important ozone depleting gas regulated by the Montreal Protocol. Their contributions were critical to a recent paper by Montzka et al. (2018) on possible illegal production of CFC-11, and to a recent meeting about the Montreal Protocol. Their jobs require meticulous work on calibration, analysis, data recording, flask repair, and interaction with station staff on issues of sampling. They have helped to continue the GMD flask record from 1977 to the present.

Fall is the time when the 'ozone hole' at the South Pole reaches its minimum. You can view up to date measurements of ozone at the South Pole Ozone Hole web page.

Study sheds light on persistent gap in natural gas methane emissions measurements

October 31, 2018
It’s a question that’s puzzled policymakers, researchers and regulatory agencies for years: How much methane is being emitted from natural gas operations across the U.S.? And why have the two main estimation methods applied across U.S. oil and gas basins always seem to disagree?

Research Groups

ccgg

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.
hats

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.
aero

Aerosols

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

Global Radiation

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

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.
obop

Observatory Operations

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