Increased water-use efficiency and reduced CO₂ uptake by plants during droughts at a continental-scale

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.
