Flux:
Reference run (longer time span): Comparison run (shorter time span):


Long-term mean natural (biosphere + ocean + fire) flux from CT2022 compared to CT2019B, including average fluxes computed over common time periods. The uncertainty listed is the one standard deviation level from the ensemble Kalman filter estimate. Units are PgC yr-1. Differences greater than 0.2 PgC yr-1 between fluxes computed over common time periods are highlighted with red text.
Recent CarbonTracker releases are composed of independent inversions using different sets of priors (see documentation). We offer the ability here to explore the influence of these different priors. Please contact Andy Jacobson for more information.
