Abstract:
This data set consist of a single netcdf file with a set of optimised global surface carbon fluxes (CO2), estimated by variational inverse methods using the TOMCAT chemical transport model, and the INVICAT inverse transport model. We assimilate in-situ surface flask observations from global surface observation sites and Amazonian lower-troposphere vertical profiles of CO2. The vertical profile data used here are available at PANGAEA Data Archiving, at https://doi.org/10.1594/PANGAEA.926834 and more details could be found at Gatti et al. (2021). These surface fluxes are monthly mean values for total emissions (labelled TOTAL_FLUX) on the (approximately) 5.6-degree horizontal model grid. The associated uncertainty for the flux from each grid cell is also included (labelled TOTAL_FLUX_ERROR). The fluxes and uncertainties cover the period of January 2010 to December 2018 and units are gC/m2/day, and time units are days since January 1st 2010. Further details about the data can be found in Basso et al. (2023) in the documentation section.
