This zip file contains 7 individual CSV files with annual mean numbers for Net Ecosystem Exchange (units of PgC/yr), and discrimination for δ¹³C of vegetation (units of ‰). These numbers are averaged over all Northern Hemisphere land grid boxes of each model. The values available correspond to those used in the 2018 Nature Geoscience publication by Peters et al.. Full description of the methodology used to create these numbers is available from the publication and its Supplement.
Each model file is identified by an acronym that is either self-evident, or can be traced back to the models in Figure 3 of the paper. The label "inv" refers to the average of the four inverse model results created.
Note that units on fluxes are PgC/yr, and the sign convention is that uptake from the atmosphere is negative. With that convention, GPP is always negative and respiration always positive. For NEE a -2.5PgC/yr flux means the uptake of 2.5 PgC by the biosphere. The provided dates have Dec 31st and MM/DD but only the year is significant in the series.
Note that for the JULES model (jul_data.csv) the NEE numbers are offset by about 12 PgC/yr due to an unintneded imbalance in GPP and respiration at steady-state. Interannual variations of Ci/Ca, GPP, and NEE are still credible and used in the analyses.
CSV files were created using python Pandas
