Table 1 Annual GPP optimisation performance metrics – mean across different regions and PFTs (with a grid cell fraction greater than a given fraction – see Methods): (i) Columns 2 and 3: prior and posterior mean annual GPP (2007–2011) in PgC; (ii) Column 4: % reduction in the annual GPP uncertainty (1σ) (2007–2011); (iii) Columns 5 and 6: prior and posterior mean monthly correlation between GPP and SIF (2007–2011) at global scale and for each biome. Biomes are based on the Köppen-Geiger (KG) classification derived by Peel M. C. et al.53.
