Agricultural Green Revolution as a driver of increasing atmospheric CO2 seasonal amplitude

A project supported by CPO’s Modeling, Analysis, Prediction, and Projections (MAPP) and  Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) programs has had new research published in Nature.  The paper, “Agricultural Green Revolution as a driver of increasing atmospheric CO2 seasonal amplitude,” was published in the journal’s Nov. 19, 2014 issue.

New study explains wintertime ozone pollution in Utah oil and gas fields

Chemicals released into the air by oil and gas exploration, extraction and related activities can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed federal health standards, according to new NOAA-led research, published online Nature. CPO’s AC-4 program supported this research.

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.

Airborne measurements confirm leaks from oil and gas operations

During two days of intensive airborne measurements, oil and gas operations in Colorado’s Front Range leaked nearly three times as much methane, a greenhouse gas, as predicted based on inventory estimates, and seven times as much benzene, a regulated air toxic.

Contribution of sea surface carbon pool to organic matter enrichment in sea spray aerosol

Research funded by CPO’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) program was published in Nature Geosciences.  The article assesses the relationship between the organic carbon content of sea water and freshly emitted sea spray aerosol in the North Atlantic as well as the coastal waters of California.
