A recently published study by the CPO’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) program details research that used in situ measurements to quantify methane emissions from various sources in the Four Corners area.

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. 

NOAA's Climate Program Office released its FY15 Annual Report on March 11, 2016. The report gives an overview of CPO's achievements  in FY15 and highlights the great work done by the Office's Divisions and Programs to advance scientific understanding of climate and improve society's ability to plan and respond to a changing climate.

A new study supported by AC4 and published in Science of the Total Environment explores the biophysical implications of future human settlement expansion. Reinmann et al. use EPA’s Integrated Climate and Land Use Scenarios model to project changes in Massachusetts through 2050.

Research supported by CPO's Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) program was recently published in the Journal Environmental Science and Technology. The paper by Lin et al. focuses on the poorly-understood formation mechanisms of atmospheric brown carbon (BrC) chromophores.
