Terrestrial gross primary production (GPP) is the largest global CO2 °ux driving several ecosystem functions. We provide an observation- based estimate of this °ux at 123§8 PgCa¡1 using eddy covariance °ux data and various diagnostic models. Tropical forests and sa- vannahs account for 60%. GPP over 40% of the vegetated land is associated with precipitation. State-of-the-art process-oriented bio- sphere models used for climate predictions exhibit a large between- model variation of GPP's latitudinal patterns and show higher spa- tial correlations between GPP and precipitation, suggesting the ex- istence of missing processes or feedback mechanisms which attenu- ate the vegetation response to climate. Our estimates of spatially distributed GPP and its co-variation with climate can help improve coupled climate-carbon cycle process models., JRC.H.2-Air and Climate
