Carbon Tracker CT2016 released

Average ecosystem fluxes. The pattern of net ecosystem exchange (NEE) of CO2 of the land biosphere averaged over 2001-2015, as estimated by CarbonTracker CT2016. This NEE represents land-to-atmosphere carbon exchange from photosynthesis and respiration in terrestrial ecosystems, and a contribution from fires. It does not include fossil fuel emissions. Negative fluxes (blue colors) represent CO2 uptake by the land biosphere, whereas positive fluxes (red colors) indicate regions in which the land biosphere is a net source of CO2 to the atmosphere. Units are gC m-2 yr-1. (Credit: NOAA)

The NOAA Earth System Research Laboratory (ESRL) Global Monitoring Division (GMD) recently released the CarbonTracker CT2016. The CPO Atmospheric Chemistry, Carbon Cycle, and Climate program’s efforts complement those of scientists from the NOAA/ESRL Global Monitoring Division by supporting extramural scientists focused on various improvements to CarbonTracker.

The CarbonTracker is a system that produces quantitative estimates of atmospheric carbon uptake and release for North America and the rest of the world. Policy makers, industry, scientists, and the public need accurate carbon dioxide flux information to make informed decisions related to atmospheric greenhouse gas levels. CarbonTracker is designed to supply that information. 

The updated CarbonTracker 2016 is available at:

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.
