Atmospheric CO2 data from the Australian Grains Free Air CO2 Enrichment (AGFACE) facility

Abstract

Within the Australian Grains Free Air CO2 Enrichment (AGFACE) research program, several facilities were established at different field sites near the towns of Horsham (36.752 S, 142.114 E; 127 m elevation), and Walpeup (35.121 S, 142.005 E; 94 m elevation) in the state of Victoria Australia from 2007 – 2017. These included: TraitFACE, SoilFACE, WalpeupFACE, VegeFACE, and NFACE. These facilities were designed to answer a range of research questions to understand the impacts of elevated CO2 (e[CO2]) on crop physiology and production. To this end, FACE ‘rings’ (octagons) were built to elevate atmospheric CO2 to 550 µmol/mol expected by 2050. These rings were open structures allowing crops to gr..
