CarbonTracker-CH4: An assimilation system for estimating emissions of atmospheric methane

CarbonTracker methane, an off-shoot of NOAA's highly successful CarbonTracker, which was partially funded by CPO's AC4 program, has earned peer-reviewed status with a recent paper in Atmospheric Chemistry and Physics.

Airborne measurements confirm leaks from oil and gas operations 7 May 2014

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 18 March 2014

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.

AC4 funds research that proposes revised mechanism for isoprene chemistry 5 November 2013

AC4 funds research that proposes revised mechanism for isoprene chemistry

A recent study by Jingqiu Mao of NOAA's Geophysical Fluid Dynamics Laboratory and his colleagues published in the Journal of Geophysical Research focused on the complex relationships that control chemistry and atmospheric transport of isoprene and related compounds.

AC4-funded project publishes paper on marine stratocumulus cloud formation 21 October 2013

AC4-funded project publishes paper on marine stratocumulus cloud formation

With funding from CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4), researchers at the U.S. Department of Energy’s Pacific Northwest National Laboratory sought to understand why some marine stratocumulus clouds form “open cells” while others form “closed cells,” even when the background whether conditions are similar.

ABOUT OUR ORGANIZATION

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2011, the United States experienced a record high number (14) of climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 670 lives, caused more than 6,000 injuries, and cost $55 billion in damages. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
