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

CarbonTracker methane, an off-shoot of NOAA's highly successful CarbonTracker, has earned peer-reviewed status with a recent paper in Atmospheric Chemistry and Physics.

The NOAA CarbonTracker-CH4 Data Assimilation Product has been developed as a companion product to NOAA's CarbonTracker (CO2), with the goal of producing quantitative estimates of emissions of methane to the atmosphere from natural and anthropogenic sources for North America and the rest of the world. CarbonTracker-CH4 emission estimates are consistent with observed patterns of CH4 in the atmosphere.   

A recent paper partly supported by CPO’s AC4 program represents the first peer-reviewed documentation of this effort. A copy of the publication can be found at: www.atmos-chem-phys.net.

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 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
