Journal ArticleDOI
A free‐air enrichment system for exposing tall forest vegetation to elevated atmospheric CO2
TL;DR: A free-air CO2 enrichment (FACE) system was designed to permit the experimental exposure of tall vegetation such as stands of forest trees to elevated atmospheric CO2 concentrations without enclosures that alter tree microenvironment.
Journal ArticleDOI
Next generation of elevated [CO2] experiments with crops: a critical investment for feeding the future world

TL;DR: A new generation of large-scale, low-cost per unit area FACE experiments are proposed to identify the most CO(2)-responsive genotypes and provide starting lines for future breeding programmes to realize the potential for yield gains in the future.
Journal ArticleDOI
Design and application of a free-air carbon dioxide enrichment facility
TL;DR: A free-air (chamberless) carbon dioxide enrichment (FACE) system has been developed by Brookhaven National Laboratory (BNL) to provide controlled fumigation conditions while minimizing the potential to impose a discernible chamber effect as discussed by the authors.
Journal ArticleDOI
Growth and yield of cotton in response to a free-air carbon dioxide enrichment (FACE) environment
J.R. Mauney,Bruce A. Kimball,Paul J. Pinter,Robert L. LaMorte,Keith F. Lewin,J. Nagy,George R. Hendrey +6 more
TL;DR: In this article, free-air CO2 enrichment (FACE) technology was used to expose a cotton crop to 550 γmol mol−2 CO2 throughout the growing seasons of 1989, 1990 and 1991 in fields near Maricopa, Arizona.
Book ChapterDOI
Free air carbon dioxide enrichment: development, progress, results
TL;DR: The Free-Air CO2 Enrichment (FACE) system at Brookhaven National Laboratory (BNL) has been used to study the effects of CO2 enrichment on vegetation and natural ecosystems, and the exchange of carbon between the biosphere and the atmosphere as discussed by the authors.
