Bakken Oil Field emitting roughly 2% of Earth’s ethane, says new report
New research in Geophysical Research Letters and partially funded by CPO’s AC4 program found that the Bakken Formation, an oil and gas field in North Dakota and Montana, is responsible for roughly 2 percent of the globe’s ethane–about 250,000 tons per year.

Semi-arid regions may be key to understanding and predicting variations in the land CO2 sink
Terrestrial ecosystems pull about one-fourth of anthropogenic CO2 emissions out of the atmosphere per year, serving as a sink for CO2 since industrialization.
The Chemistry of Atmospheric Brown Carbon
A team of scientists partially funded by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program published a Chemical Reviews article on the chemistry of atmospheric “brown carbon,”– the atmospheric aerosol contributing to the brown color of smoggy air.

Pollution in urban vs. oil and gas producing regions
A multi-institution collaboration of scientists, including those from NOAA/ESRL/CSD and those partly funded by CPO/AC4 program has resulted in an interesting study comparing the origins of similar levels of formic acid (a potential precursor to aerosols) in very different environments.

Direct measurements of methane emissions from abandoned oil and gas wells in Pennsylvania
New research supported by the Climate Program Office’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program was published online in the Proceedings of the National Academy of Science on Dec. 8, 2014.
Modeling regional aerosol variability over California and its sensitivity to emissions and long-range transport during the 2010 CalNex and CARES campaigns
A new paper: “Modeling regional aerosol variability over California and its sensitivity to emissions and long-range transport during the 2010 CalNex and CARES campaigns,” has been published in the Journal for Atmospheric Chemistry and Physics. CalNex (the California Nexus, Research at the Nexus of Air Quality and Climate Change) is a 2010 field program funded by state of California and the Climate Program Office’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program.
