• Observations and flux estimates for 2010
• Revised flux estimates for 2000-2009
• New CO2 observational data:
  • New and revised daytime average data have been added for the Lawrence Berkeley National Laboratory (LBNL) site at Southern Great Plains, Oklahoma, United States (SGP_03C3) for the period 2003 through September 2010.
• Multiple priors: CarbonTracker now consists of eight independent simulations, each using a unique combination of flux priors. This represents a factorial design experiment to explore the sensitivity of CarbonTracker results to the influence of the first-guess flux.
• Mole fraction data are now provided in netCDF-4 format, using internal compression. This change may require an update to your analysis software.
• ESRL has switched to a new FTP server, and downloads for CarbonTracker are now available at the new URL /gmd/aftp/products/carbontracker/co2.
• Revised Executive Summary.
